Re: Linx 12x64
It depends on what you are trying to do with it. For a lot of verticals or simple office document editing, it should be more than enough. I had an Atom based Samsung tablet for a while. It wasn't a speed demon, but fast enough for Word, Excel and Outlook and the odd Store game.
Obviously, if you are going to be installing Gentoo on it and compiling everything as you go, it is going to be a real slug.
