This is off-topic, in that it's not Debian-specific, but it's relevant to people wondering what kind of laptop they should get. I've had good experience with Debian on my Sony VAIO, until now.
The hardware broke, it's a US model, I'm in the UK, and Sony's international support really really sucks. So, if you're sure you'll never leave the continent you buy it on, go ahead and get a Sony. But if you want to be able to travel with it, I'd suggest going with a more international company. For details of how they suck, read my web page. http://www.thehouse.org/~seth/laptop/ Apologies for this somewhat off-topic ranting. I'm cranky from having to use clunky old Solaris machines instead of Debian.
