I thought I'd check out the specs on the A510. I was not happy that the fullsized USB was not there. So I've made my decision that I will not upgrade to an A510 and ACER can bury that in their vault. So I had a look at the A700. Yes similar featured like the A510 and miniUSB too. So all things said, if I'm even thinking of upgrading it will be the A700/A701 for sure. Why take a step backwards with the A510? That is my opinion!
