Final Words
I always feel like I need to congratulate or somehow gift those readers who make it all the way through an article like this. Maybe I'll start handing out lollipops one day. If you made it this far you'll know that there's a lot of concluding that needs to happen.
First, the phone itself. Honestly, if you have the original iPhone then this is absolutely the one you'll want to upgrade to - you'll feel like you've been swept off of your feet one more time (assuming you did like your iPhone). Upgrading from the 3G is also a good idea in my opinion, just because of the tremendous increase in performance. Where the upgrade recommendation becomes stickier is if you have to pay full price for the phone. Unlike the iPhone 3G launch, AT&T isn't letting everyone move to the 3GS at the $199/$299 upgrade price (16/32GB models). Under immense pressure from the market, AT&T has made terms a little more favorable but there is a sizeable population that won't get upgrade pricing until later this year. At $500 or $600 I'm not sure the 3GS is worth the price today, simply because I'm expecting an updated model around this time next year. Remember that Cortex A9 based phones will be out in 2010 and Apple also has the option of using a multi-core A8 variant as well, especially at 45nm. If you have to spend that much money, either wait until the next iPhone or wait until your upgrade price drops; $500 can buy you a Core i7, it shouldn't be the cost of a CPU upgrade for your phone.
Next, there's the Palm Pre. I continue to be impressed by not only how much Palm was able to do in such a short period of time with webOS but how frequently Palm is updating the OS on the recently launched Pre. We're now up to four OS updates since its launch in June and I fully expect more from the Palm crew. By the time the Pre debuts on Verizon and AT&T the phone should be sitting pretty. If you don't mind being on the bleeding edge of a platform that needs work and real developer support, the Pre is a real alternative to the 3GS - and in some senses, a better device to use.
Finally, there's the hardware itself. The real story behind the 3GS isn't that Apple took longer than necessary to move to the Cortex A8. No, the real story here is that both ARM and Imagination Technologies are significantly improving the CPU and GPU performance in high end smartphone SoCs at a rapid pace. There's significant room for improvement in both CPU and GPU performance, right now all we're limited by is power consumption. Within the next year we should see more SoCs transition to 45nm and at that point I'd expect to see multi-core ARM implementations as well as wider PowerVR SGX cores. Then there's always ARM's Cortex A9, the first out-of-order ARM core. In the distant future we also have to start thinking about Intel; Atom was always intended for the smartphone market, and at 32nm I'd expect to see an Atom based CPU in an iPhone-sized device.
If you're bored by performance improvements on the desktop, then keep an eye on the ultra mobile space. Smartphones are going to see significant performance gains over the next few years. The iPhone 3GS is just the beginning.

My wife actually offered to give me her 3g if she got the the 3gs but I didnt think it was worth it. She asked me this morning how it was better and I didnt know (didnt admit it of course)Now I want her 3G "free" and she really does need the 3gs since since is always multitasking/social/mail..me, including aim.
I thought the 3gs would have some radical new gps stuff but the compass is not impressive. Nothing to get me geeked on to the tune of $200. For my purposes having the older iphone would make travel and remodeling job estimating easier over my tattered razr.
My media mogul mamacita however needs that sleek new 3gs like yesterday as every gripe she has about the 3g phone seems to have been addressed somehow.
Great write-up!
Only regret is when I saw the new screen and sleek size of the 3gs at the apple store a couple days ago it does screem "arent I beautiful?" but that is what apple does so well right?

Give the magic, or hero another chance!Your numbers for those phones are whacked, its faster than the 3G at alot of things. Try to kill all the backgroundapps. (yes, it multitasks)

Very good analisys.I was just surprised ARM CPUs still made on 90nm and 65nm. With the performance and power saving 55nm and 45 nm processes i would imagine they would jump the bandwagon fast.

Some people can't drop $600 in a lump or $2600 over 3 years on something as stupid as a cellphone. No matter what it can do.Besides the fact that Apple is killing all support for proper hardware acceleration and access to OpenGL 2.0, whatever.
Can we get more Android and G1 coverage? Please?

Like the guy above said, you buy a phone, you either pay a lot upfront, or you get it with a contract. Either way you'll still need to pay a ton of money each month to for your voice and data. You could get a cheap phone that only makes calls and costs almost nothing, but that's not the same is it?And what's this about apple not supporting hardware acceleration / opengl es 2.0??? Almost everything in the gui is hardware accelerated. And there's very good opengl es 1.1/2.0 support in the sdk, hence the ton of hardware accelerated games. There may not be much supporting es2.0 yet, but that's because the first 2.0 capable device has only just been released.

You know what? The cost is:$199 up front
$70 / year * 24 months
= $1680 + $199
But let's face it, most of you already have cell phones. A quick look at a WinMo phone like the HTC Touch Pro is $70 / month too at minimum ($39.99 voice + $30 data. Same with a Blackberry.
SO WHY THE HELL ARE YOU COMPLAINING?
So if $1880 is too much for you, don't get a cell phone period.
Stop complaining. The iPhone is actually pretty damn cheap. You're locked in a contract, but even if you had another phone WHY WOULD YOU GO DATALESS?

i'll care about the iphone/ipod when they start sporting VGA screens. if my digital camera can have a 3" 640x480 display, so should these overpriced toys.psonice - Friday, July 10, 2009 - link
Higher res screens look pretty, but 640x480 needs 2x more power to fill than 480x320. The screen is more than acceptable already, so I'd take faster running apps/games and longer battery life over more pixels any day.Kougar - Thursday, July 9, 2009 - link
Thanks for the informative crash course in CPU instructions, that filled in some gaps I didn't understand. It's nice to now understand how some aspects of the design fit into or affect the rest of the design.Unfortunately, you've only drummed up the excitement factor for Intel's Sandy Bridge... from some general info that's been around and based on what you've given it sound like the potential is very much there for some very significant performance jumps. So much for Gulftown's allure!

I love the attention to detail when describing the CPUs and the graphics processor and stuff. Very cool. I hate that other people are dissing the iphone hardware. If you don't like Macs rules get a pre. Plain and simple. I for one support these people that want to sell their apps for a good price and are trying to make it big in the dev world. Kudos and I will buy your apps.I will be honest, I am sick of the multitasking argument. You do hit on a point that needs to be addressed imho by Apple and that is that there is no good app for chatting. I really think that Apple needs to include their own IM App that stays on in the background (if you want it to) and collects all your SMS, MMS, IM, facebook, Twitter, etc messages. This would be great. While it would be great I recognize that this would totally sap the power on the iphone. If you had all this info push to your phone, the servers would be constantly sending you messages every second. As for multitasking, I don't really care to have it. There are areas where I wish I had it but it is not necessary. Not to mention that the palm pre has a horrible battery life...plain horrible. I hear people talk like they need 3 backup batteries just to get through the day.
I have noticed myself that the compass is a little sketchy. There was a time on 07/04 that a friend and I were lost in the city walking around and we used my maps app to find where we are and I tried to get the compass to work to make reading the map easy and it wouldn't work. The map wouldn't rotate and it was frustrating. Oh well.
Your review of the camera was spot on. It will never replace my uber camera but when I am out and about doing whatever it does great for quick and easy pics. And the movie functions are awesome as well. Now if only you could cut out middle pieces of a movie. Hopefully soon.
I love the speed of the 3gs. I notice, not tested but notice, a large speed increase and I absolutely love it.
The one major place the 3GS has over the pre is the App store. No company has been able to implement an app store like Apple. I get all my multimedia from one source (itunes) which is great....Movies, podcasts, video, audio, apps, etc...all in one place is the best thing that apple has done in forever. I will not argue prices or app submission ethics because I truly believe that apple keeps the People as their top priority.
Great article.
