Don't get me wrong, I eat Linux for breakfast since I've been working with it professionally for more than a decade.... but.....

Linux as a UI/desktop generally sucks. Linux as a PDA sucks worse. Sure it's some geeky goodness working with it, but at the end of the day the PDA functions still stink. Desktop is passable these days as long as you don't need to deal with word documents or deal with Pro Adobe products. The PDA functions will probably never really get worked out until Gears brings Google Calendar to the table.

I'm not saying it's impossible to get it into a workflow, but I have better things to do with my weekends.
