This is coming from someone who owned a 1g, and never used a 2g, so my opinions might be a little different from 2g users. First thing I noticed was that it's noticeably lighter than the 1g. The screen also has a smoother feeling to the surface, and doesn't seem to show fingerprints as much as the 1g screen. I installed all my apps, music, photos, and videos on it, and ran through some tests. Speed/Graphics: I noticed a huge difference in speed. Apps start up quicker, and games load faster. I ran a few 3D games, like homerun race, imech, f.a.s.t., and wildwest poker, and the graphics are much more crisp, and smooth, and have a much better framerate with the updated gpu. My 1g would often lag if I flicked through the coverflow view, or picture gallery too fast. So far it breezes through this without a hitch. I ran through some websites like CNN, clicking on links, and web page browsing seems to be twice as fast. I also use an app called speedtest, that tests your download/upload speed, and it scored much higher than my best scores using the 1g. i'm assuming its due to the new NIC. Another main reason I upgraded was my 16gb was full. Now with all my media I still have plenty of space left. No big surprise there. So far the only complaint I have with it, is that the voice control feature was very hit or miss for me. When I would ask to play a certain artist or album, it would play something different. Maybe i wasnt talking loud enough, or my voice is funny, but it was sketchy. Not a big deal for me since I don't plan on using this very much. I also tried out voice memo and that worked out fine, with good sound quality on the clips. I also wish that it came with a wall charger. Apple brand, or decent 3rd party ones cost 25-35. When i'm playing apps or watching videos on the couch, i'm too far from my computer to charge it with just the USB cable, so i pretty much had to spend a little more and get the wall charger. Startup/shutdown time is faster, as well as app browsing, and itunes video/song previews. So aside from the 2g updates I wanted (external volume control, built in speaker, and bluetooth support) it comes as no surprise that the biggest draw here is the increased speed and improved graphics, as well as the better storage/price points.
