The camera units are the same. The one installed in the photo just has a removable foam piece for light insulation. It exists on the black iPhone 4 as well.

First thing, there isn't that distinction anymore. RISC originally meant that the processor had fixed width instructions (so it wouldn't have to waste time asking the software how big the next instruction will be). CISC mean that the processor had variable width instructions (meaning time would have to be taken to figure out how long the next instruction is before fetching it.) However, Intel has addressed this problem by making it possible for the processor to switch to a fixed-width mode for special processor intensive purposes. The PowerPC is stuck with fixed-width and has no ability to enjoy the flexibility of variable-width instructions for non-processor-intensive tasks. This means that CISC is now better than RISC. (Using the terms to loosely define Pentium as CISC and PowerPC as RISC.)
Originally it was Reduced versus Complex instruction set computer. Making simpler processors go faster is generally easier than making complex processors go faster as there is less internal state/logic to synchronise and keep track of. For any given fabrication technology, this still generally holds true. Intel managed to sidestep this principle by investing massive sums in their fab plants, effectively meaning that the fab processes being compared weren't the same.
The opposite end of the spectrum from RISC is arguably the VAX line. With this instruction set, massive complexities arose from the fact that a single instruction took so long and did so much. It was possible for timers, interrupts and "page faults" to occur midway during an instruction. This required saving a lot of internal state so that it could later be restored. There were examples of performing a given operation with a single instruction or a sequence of instructions that performed the same effect, but where the sequence achieved the join quicker because the internal implementation within the processor was able to get on with the job quicker because it was actually a simpler task being asked of it.
The idea of fixed sized instructions isn't directly coupled to the original notion of RISC, although it is only one step behind. One of the basic ideas with the original RISC processors was that an instruction should only take a single cycle to complete. So a 100MHz CPU might actually achieve 100M instructions per second. (This was often not achieved due to memory latencies, but this isn't the "fault" of the processor core). In this context, having a variable length instruction means that it is easy for the instruction decoding (especially if it requires more than one "word") to require for effort than any other aspect of executing an instruction.
There are situations where a variable width instruction might have advantages, but the argument goes that breaking the overall task down into equal sized instructions means that fetching (including caching, branch predicting, ec) and decoding these instructions becomes simpler, permitting optimisations and speed gains to be made elsewhere in the processor design.
Intel blur RISC and CISC into gray by effectively executing RISC instructions internally, even if they support the apparent decoding of CISC insructions. They only do this for legacy reasons.
Apple will never switch to IA32 (Pentium) because 32 bit processors are a dead-end and maybe have a couple years left. The reason is because they can only have a maximum of 4 GB of RAM [ (2^32)/(1 Billion) = 4.29 GB ]. This limit is very close to being reached in current desktop computers. Apple MAY at some point decide to jump to IA64 in my opinion, and I think they should. Obviously the Intel family of processors is unbeatable unless they have some sort of catastrophe happen to them. If Apple jumped on they'd be back on track. Unfortunately I don't believe IA64 is yet cheap enough for desktops.
I think this "unbeatable" assertion requires some qualification. It may be that Intel will achieve the best price/performance ratio within a suitable range of qualifications, but this is different from always achieving best p/p ratio whatever. Indeed, IA64 versus Power4 is going to be an interesting battle because Intel has bet on ILP (instruction level parallelism) whereas IBM has bet on data bandwidth. Ultimately (and today!), I think IBM's bet has more going for it. But that's if you want ultimate performance. The PC space is often characterised by people apparenntly wanting ultimate performance but actually always massively qualifiying it with severe price restrictions (such as less than 5 digits to the price).

What does ANY of this have to do to Apple rejecting a Pulitzer Prize-winning cartoonist from the App Store?
Probably the same reason "what does the original post have to do with the Pulitzer Prize winning cartoonist getting his app rejected." This person was merely commenting on another posters post.
I am waiting to see if the app gets rejected a second time before I lay judgment.

The iPhone 4 was and still is the best
Well, if we were vehement about dismissing their review of the iPhone 4 as flawed then shouoldn't we be consistent and do the same for the iPad. If they're not worth paying attention to because of bad review then why laud them for picking the iPad as the best tablet. I'm just say'in.

I'm glad I read some reviews- I was about to try the contact syncing. In retrospect, that was stupid to even consider. I have a lot of value in my address book- info collected over many years. Why would I (1) send all that data to Facebook (do they keep it? do we know?) and (2) let said 3rd party app have run of the house, updating/deleting any and all of my contacts?
Like I say, I almost did it. But it would have been stupid. I *might* have been saved my MobileMe since I'm usually notified before it updates a given percentage of all my data. But still- a risk I don't want to take.
You fully, and completely misunderstand how the app works.
Sorry for your ignorance.
FYI.. no contact info is added or deleted.
Only contact pictures are synced, and a link to the persons profile is added as a webpage link in your contacts.
NOTHING is deleted
NOTHING is overwritten (unless you want to overwrite existing pics) - that's an option you chose.
the data is sent to facebook in order to "match" contacts by both name and email address.
What facebook does with the data... I assume nothing. you assume they share it. I suppose that topic is open for debate

If you ask me, it's pretty clear Apple will update all of its laptops before the holiday season. I personally can't wait to buy a new MB, because my 600 MHz G3 iMac is getting a bit sluggish. My question is this: Will it be a simple CPU upgrade, or will Apple change pricing and/or other hardware (such as HD capacity, RAM, etc.)? Oh, and how long do I have to wait?
They're switching from ASUS to Foxconn so hopefully you'll get a Macbook that doesn't turn off Randomly in the middle of important work.

The Intel Itanium. Granted, it's not for consumers per se, but it's still for high-end consumers. Compare that with Power Mac G4s.
NT can do up to 32 processors per machine as of the Windows .NET family.

The Slim design isn't going to trickle down to the other models?
If I were to guess, it would be this single new model alone for the rest of this year, with the 2 older models slotting in as the "bargain" versions for the holiday season. Then next year, after the launch of Kinect has settled in, and the older models are pretty well phased out, they could introduce a wider range of models.

the iPad will be for normal people when you don't have the sync it.
all this syncing ********* needs to stop.
I shouldn't need another computer to use my iPad.
Makes no sense at all.
True
But do you really need to sync it though?
The apple store will activate it apparently if asked,
and I can't see people having much problem yet if they haven't synced from day 1.
So its possible to own an ipad without a computer.
Only becomes a problem when too many apps require a later OS version

I really hope T-Mobile isn't chosen...I had them for a year and a half and what horrible customer service. Not to mention that their coverage in Palm Springs, CA is horrible. Apple should go with Verizon, I did go with AT&T myself, but Verizon is rated highest of all the carriers for customer satisfaction and coverage.

Hi everybody,
at the moment I've got an old non unibody MacBook Pro with an ACD like in the picture below. As apple has switched to the unibody models they started to put a black bezel on the the ACDs and a black keyboard to the MacBooks. What I love about the silver-only-design is, that the content on the screen is much more dominant, the MacBook and the ACD seems to fade away when you are working with them. I just wanted to know what you think about the new vs. old design.
Regards
Dave
Well, I will voice my opinion and here it is: I like the unibody screen with the black bezel better. I like the black keyboard and the silver bezel though. :) Now, the black keyboard looks 10 times better than the silver/white keyboard. Just my .25 though.
I am new to Apple and I am not very nostalgic about old Macs. Maybe in a few years I will like the current model more than the future model. :eek: What a mouth full!

It would be nice if this worked in the other direction as well--i.e., from a computer to an iOS/AirPlay device. (Yes, I know about AirFoil and friends.)
EDIT: Wait, can Home Sharing in 4.3 do this? (I don't have a 4.3 device...yet.) If so, I guess I can expand my wishlist to include non-iTunes media... :)
For your non iTunes video, check out this (http://itunes.apple.com/us/app/air-video-watch-your-videos/id306550020?mt=8) app. I have it and really like it. You set it up on your computer, tell it where to look for supported video files, download the app on your iDevice, and streaming begins.
There is even functionality for converting to iTunes format, though I haven't messed around with that much, so I can't speak to its effectiveness.
Best 3 bucks I've spent on the App Store.
EDIT: Didn't see this response ahead of mine. Almost word for word...
You should check out Air Video (the iOS app). It's the best solution I've found and with iOS 4.3 it works great for streaming all the .avi and .mkv movies on my HD to my apple TV via my iPhone.
It goes (Air Video server on computer) -> iOS device -> Apple TV.
It was probably the best $2.99 I've ever spent.

I've had general anesthisia about 11 times now (long story ...).
The gas is fine i remember once the anesthitist asked me to count to 10 whilst he put the mask over my nose and mouth. ( i reached 3 or so :D)
The IV isn't much worse (and i'm not a huge fan of needles!).
You do feel pretty groggy afterward when you come to, well i least i did, and its definately worth getting someone along to help take you home. They could just be there to pick you up and make sure you get into bed ok when you get home. You'll prob be asleep for a good 10 hours after that.
On the whole the administration of the anesthetic is not unpleasant.
Best of luck with your surgery iGary
Unless they keep me overnight, I'm having the midshipman I sponsor from the Naval Academy pick me up and get me settled at home. I'm sure I'll be just fine - I'm just a worrier. :rolleyes:
