Let the hive mind of Engadget get that for you.
"As someone who doesn't reside in the USA, I was wondering what would be the best way to get internet for my computer in the US for a couple of weeks? If it were Europe I know I'd look for some prepaid data. Is there anything similar offered by American carriers? A MiFi or a data SIM that I can tether from would work, but I'm trying to maintain a tight budget. Help!"
Yes the VGA display is 4 times the resolution of QVGA, but also probably 4 times less battery life. There are reasons most handhelds still use QVGA and one of them is more efficient power consumption.
I'm guessing you've never used one. I've used the HTC VGA model and the battery life wasn't that much worse than my 6700. I'm not saying it was equal but not that much less - not half as long and certainly not a quarter as long. The battery was about the same size.
