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.

MacWorld, quarterly report and market in general. Expectations of MacWorld beyond reality and can't top iPhone. Quarterly report also not up to predictions.
To be correct - it wasn't so much the quarterly earnings but the outlook. There is a huge concern in the market that the US economy is not only slowing down but heading towards a regression.
What is everybodys guess ? How deep will they fall ? Below $108 ? Below $125 ? I already have some and want to buy more. Its always nice to hit the low point.

Why are you trying to turn the assault into bullying / an LGBT hate crime? I know MacRumors PRSI is obsessed with the issue, but there's no evidence for it.

This doesn't spell doom for anyone or anything. Companies that are afraid of competition usually never stood much of a chance in the first place--Mr. Jobs has thrived under these conditions over the past 5+ years, I would expect nothing less now.

well done.
it is macrumors, after all.I enjoy idle speculation about this stuff as much as the next guy but I still think the old 'everyone is entitled to his own opinion, but not his own facts' thing should probably be adhered to (and I hope that doesn't come across as snarky to the original poster, and apologies to him/her for [citation needed]ing if it turns out I was wrong).
Widgets and personalization - not needed. Only nerd losers stare at their OS, being unable to find any better way to spend their pathetic empty life with no purpose.Waiting for you to change the tone when Apple comes out with widgets and custom personalization.You sound like I am against it.Can we take that as an admission that you're a nerd loser who is unable to find any better way to spend his pathetic empty life with no purpose? :D
If you are, don't worry, we all post here too...
I couldn't quite tell if your post was serious given how you followed up on it, but I think having better notifications and making better use of the home screen might be quite high priorities from a user-experience point of view. Wouldn't it be helpful to see a Gmail-style snippet of your new emails visible when you unlock your phone? Or possibly a small calendar display so you can see at a glance that there's a meeting you're booked into later? I guess it might be difficult to integrate these things without dramatically reducing the space visible for apps but I can imagine a lot of people having a use for this kind of functionality and Apple is denying people the choice at the moment.
I still don't quite understand why people are so averse to the idea of a visible file system, as though this means you're going to have to poke around in a directory structure to find a note in Notes, or a song in the iPod or somesuch. It's adding functionality for those who want to use it, not complicating things for people who don't want to use that side of things. I'm sure Apple has the engineering talent to do it.

Don't discount microsoft - they have money to lose for years in trying to get #1 for MP3 - slowly they creep up and overturn Apple - apple doesn't ahve the same stamina.
A long term commitment, not a short term thing.
That's what worries me. They don't get #1 by being the best, they get to #1 because they can lose money for years and drive the competition to the ground. Look at the Xbox and Xbox 360 as a perfect example. They're still in the red, no a single cent of profit from the two consoles.

Up to the point, RacerX...I am tired of these "security warnings" that carry little more than vaporware and a thirst for publicity and hacker-like "fame"...
If a kernel panic is a "serious issue", think again...and go Vista...and please, no market share arguments anymore...we have probably more than 50 million Apple users out there...I am sure a few hackers are still trying hard to make a virus in the wild for them.

This quarter, Macs accounted for $2.213 billion in revenue. iPods accounted for $1.559 billion, plus another $452 million in music-related revenue, for a total of $2.011 billion. So, even without counting Mac peripherals and software, music revenue was less than Mac revenue.
Last quarter, Mac revenue was $1.866 billion, while iPods sold $1.497 billion, plus another $457 million in other music-related revenue, for a total of $1.954 billion for the music end.
Got it, thanks. Makes sense now that I read the PDF on Apple's site.

Seriously, why not an Imac with touch-screen right now? Will we need to wait for the next iMac update to see this technology implemented?
Are you serious? Even if you were to put X on a big enough display so you could easily use it as a touchscreen, you're arm will die of fatigue in minutes. If you want a near touchscreen like experience with your new iMac, try a Magic Mouse or a Magic Trackpad.
