As with the other Acer notebooks I've looked at, the W510 features the company's Live Updater technology, which downloaded and applied a system BIOS update and a number of driver fixes in the time I was using it. All were applied without trouble. I did notice one peculiar problem involving the keyboard, which I'd expected to be fixed with an update: the Ctrl-Home and Ctrl-End keystrokes do not seem to work properly. They work fine if you use an external keyboard, but not with the dock keyboard. (Acer is aware of the problem.)
Ordinarily, I wouldn't choose Acer's Iconia W510 over the HP Envy. The Envy is better built, and though battery life isn't as good, it's still great (11 hours 15 minutes in my Netflix test). But if the price is right, the W510 is a worthy alternative.
