You are assuming that the amount of spectrum available will never change. There's a reason they just shut off analog TV. Yes, spectrum is a finite resource, but they're shifting more to mobile voice/data very soon.
You are also assuming that all the frequencies available to each tower are already in use on that tower - that the towers are saturated. I think that's an unlikely assumption, outside very dense areas like Manhattan and DC. (And in Manhattan, you probably don't have the whole "can't get towers approved because of community opposition" problem because the towers are just installed on or in existing buildings, albeit at some expense; and you probably need a denser tower population anyway because of all the ground clutter; so a denser tower population probably already exists).
I imagine that the transceivers used on the towers have channel limits - that each transceiver can only handle a certain number of handsets k, within the limits of the number of available frequency sets n (the phone doesn't just use one frequency; I'm pretty sure they are spread-spectrum devices, so you are better off thinking of frequency sets rather than frequencies), and that k <<< n . That would explain AT&T's claims that their ongoing upgrades will mitigate the problem - they may be upgrading the transceivers on the towers so that each tower can use more of the frequencies theoretically available than has been true so far.
The other cell companies also have to segregate their frequencies from one another. If T-Mobile (the other GSM/3G carrier) isn't having this problem, it means either a. their network utilization is a lot lower, or b. they're doing something right and AT&T is doing something wrong. That's also true with the CDMA carriers, of course, but I think they use different parts of the spectrum - and Verizon is a pretty big network.
It's interesting how cell service works. Here's a simplistic summary:
Only a certain number of users can use a tower at any given time. There is only a certain range of frequencies that can be used. All towers use these same frequencies. This means that each tower must not overlap the others in terms of coverage area and frequenceis. To ensure this, companies actually use different frequency ranges on adjacent towers. Further limiting how many users can use each tower.

When I was in NYC I noticed by data speeds were much slower. I didn't make enough calls to have any problems with that though.

Translation: Apple's new iPhone, code named Anorexia, couldn't possibly hold 2 chips! We aim to make a phone so thin, a postage stamp would add bulk.
Yeah while Apple realizes people want their mobile smartphone to be small and portable as that is a key part of the puzzle the rest of the industry is trying to duplicate this:

Sometimes it's pretty easy to spot trans people. It can be difficult to convincingly look like the opposite sex.

I think if there were no guns besides the law enforcements then America would be a much safer place.
Then what would law-enforcement need guns for?
It is literally impossible to get rid of guns here. The only thing gun-control does is take away guns from those who legitimately and responsibly own them. You think the guns that gangsters and criminals have are registered? I think not.

The Thunderbolt Wiki (http://en.wikipedia.org/wiki/Thunderbolt_(interface)) has a diagram showing the TB controller's access to things. The accompanying description ("Thunderbolt can be implemented on graphics cards, which have access to DisplayPort data and PCI express connectivity, or on the motherboard of new devices, such as the MacBook Pro.[5][17][22]") implies that a TB compatible PCIe graphics card could bring older systems up-to-date. That would be interesting.

For Mac users, why would we want to install Vista-(via BootCamp) and then also use it under virtualization?
On my MacBook, the BootCamp install is for software that needs direct access to the hardware and where performance under virtualization would suck. ;) I run Windows XP/Vista under Parallels to check out how the web pages that I create on the Mac side using MAMP. Seriously, who in their right mind would install IE7 on their Windows system before the first service pack comes out? :eek:

It's a great step. I can't imagine needing more speed than a Thunderbolt connection, for the next decade, IMO. Most people don't specifically need such speed, but it is good to have. As for professional use for large files and video editing: boffo. Looks brilliant.

I'd be surprised if this comes true. T-Mobile's network is not exactly up to par with AT&T and Verizon.
Yeah, T-Mobile needs to work harder if they want their network to drop calls as much as AT&T.

How has Apple NOT innovated on the Mac line up?
- Completely redesigned and absolutely beautiful architecture on the insides of the Mac Pro
- MagSafe
- 24" all in one machine
- Front Row/apple Remote/iSight in every "portable" Mac
- Two finger right clicking on trackpad
All of this in the year of a move to a new platform.
The REAL innovations though, will occur in the second generation of Intel products. THe most important thing was to make a swift but calm switchover to ensure nobody got nervous over the move. Now we are here, 2007 will be sick.
Again:
-Intel Chips are not innovation. Its change of suppliers.
-Magsafe is an actual innovation.
-24" monitors have been around for like 10 yrs.... slappig into an iMac isnt innovation its either ballsy managing or perfect timing
-A webcam.... and a software to list all ur media.... nice not new. ITS A WEBCAM PEOPLE. THATS ALL. IT DOESNT SAVE CHILDREN.
-I thought Sony had a laptop that did this already? Can't confirm.

Well if it's a platform war, Android is getting seriously spanked by iOS. The iOS platform is holding its own in smartphones and still growing in market share and in dedicated media players, portable media players, and tablets, it isn't even a contest. The iPad, Apple TV, iPod Touch and all the rest of the products on the iOS platform are seriously spanking the crap out of the Android alternatives.
That's one of the reasons why the big developers concentrate more on the iOS platform than Android.
Now did that register or are you just in denial?
The only people who lump in tablets and PMPs into the platform are apple lovers who are in denial. Everyone else separates them by device. Smartphones are compared to smartphones. Tablets to tablets, etc.

Attempted insults show your insecurity.
You're assumptions prove it.
Try your tactics on someone else :)
You are totally awesome, guy. It's not just your phone, it's a message about your whole lifestyle. I too care way more about what a stranger who sees me using a phone might think than I do how it actually works. All these dime a dozen sheep buying iPhones because they're easier to use and more elegant than Android phones are total losers. Don't they know that being seen is the most important feature of a phone? High five, man.
This is incredibly true, and hilarious.
Sounds to me like the real insecure one here is maclaptop, if thats the mindset you have going on concerning phones and image.

You don't need to keep taking computers back you know. You could try and be happy with what you already own. Also why did you buy it if you knew there were new ones on the horizon anyway?
Also, if one were to buy a Mac within two weeks prior to a new model you're entitled to just take it back for the new model, or at least that's how it used to work.

I just ordered it with 3 GB. I hope the system is not "out of balance" because of the non-even distribution of the memory banks.

Well that definitely counts me out as a potential user. (Yes i'm cheap)
Entitlement? No offense as many feel the same way. I just don't understand how some can realistically expect such a product/service to be free for how new it is.

it will be a good competition after all. it's MS. not just small mp3 player makers. but I doubt that new product will take a piece of ipod so called 'ipod killer'? it's not how ipod killer looks but how it can integerate both hardware and software like itunes so well. whatever MS do, they have gizliions of money to put anyway.
on the other hand, Apple already knows MS plan. Apple will release new 6G ipod before MS will do or at the same time. plus movie download service could be launched becasue MS makes Apple to hurry for going more further way. it will be interesting to watch the competition. :)
