Afaict it's not yet known if there will be any hardware differences between the Windows and Ubuntu models. Yes, of course you can wipe the OS in either case.

Afaict it's not yet known if there will be any hardware differences between the Windows and Ubuntu models. Yes, of course you can wipe the OS in either case. Dell's Linux extensions are open-source as far as I know, e.g. their touchpad improvements that they're working on. But you might have to build your own kernel in order to compile those drivers yourself, or perhaps wait a long time before they're mainlined. This is conjecture based on my understanding. I'd look around the Dell-Linux forums/blogs, the dev team is pretty open about discussing this stuff.
