I've been using an old Iphone 2.5g as my "ipod touch" for about the last year or so. I switched to Sprint for the cheaper rates so no more iphone coverage. Well, since the old phone is not compatible with IOS4.0 and since this new device is seemed truly "next-generation," I decided to take the plunge. I hate the lack of space on my old iphone (8Gb) so I splurged for the 64. Here's a few things I noticed right out of the gate:
1) The screen resolution is phenomenal. The lighting sucks. It has a nasty angle of view. If you look dead at the center of the screen with a black screen "on," you can see slight brightness variances from corner to corner. Not terrible, but I had expected better. After researching it a bit, this is apparently because Apple "cheaped-out" and did not include the IPS style of lighting that they used on the Iphone 4. Oh well, still a great screen though.
2) Size: The device is amazingly thin. This is both good and bad. The buttons are kind of hard to mash as they are located on the heavily beveled edges of the device. It's not bad, but, you do need to have a good grip on the device when screwing around with volume or power. It is super light and fits well in my hand though. But, as weird as it seems, i do hate how the apple logo feels under my finger. Feels like I have super glue or something on my finger tips... strange
3) Speed: The speed of the device is great. This is comparing it directly to my old iPhone though. It blows it out of the water. I don't have to really wait on anything. I do wish the browser was better though. On my old phone, when I'd scroll too fast on a large page, i'd get the checkerboard effect. I hoped this was no longer an issue with the new A4 chip. Again, after researching it, I found that the iPod touch has half the RAM of the new iPhone 4. Guess that would explain it.
4) Camera: The camera is crap. It's low res and has poor low light performance. It's cool for impressing Grandma with the Face Time app, but that's about it. Don't leave home without a good cell phone camera (or a Nikon/Canon!)
5) Minor quibbles: I miss my vibrate/loudness switch. Sucks not being able to instantly mute the device when i want it quiet. I also wish the speaker were more full. I am glad that Apple included a speaker at least, but, for it to be useful as a Face Time device for Grandma, the speaker really needs to be made louder/fuller.
in a nutshell, it's a great device, but it is the Kmart special of the new Iphone 4 in pretty much every way. Why did I give it 4 stars when I'm so harsh on it? Because, no other device even comes close. Apple has managed to make the Ipod Touch feel magic in every way.
