I got an iPhone 3G last year and it was pretty cool, but recently I was having to charge it at least twice per day. I got a replacement battery and watched a YouTube video four times showing how to do the replacement. I started the surgery and thirty minutes later the phone was destroyed. I thought about getting the iPhone 4. But even had it been available I had decided against it. I don't want another device that requires surgery in order to change the battery. Plus the storage isn't expandable. So far I like the Aria. It's definitely faster than my old iPhone. I love the fact that I just throw my music & videos into folders on the memory card and there they are in the phone. On the iPhone I'd have to boot into Windoze (I'm a Linux guy) then run iTunes, then do a sync that typically took more than an hour. Go Android!
