Build is solid and nice to hold. Display is sharp and looks very good for a 1280x800 display. Speed is great and makes my Thrive seem like a budget tablet. Game emulators are significantly faster (Fpse and N64). Sound is two speakers and best I have heard on a tablet and soon laptops. Wifi range is great. Battery life is great due to the big 9800maH battery. USB host function works with AND powers 1TB NTSF portable hard drives. This is where the big battery is real nice. 1080p mkv files play perfectly. The negatives are the right side gets really warm (not hot) and the USB location on the bottom makes no sense (should have been on side). I give the A510 an A.
