Mine's a Dell lappy - soon to be a "flying out the window" lappy if it doesn't start behaving itself. I have (so far) resisted the urge to whack it one.
A really really crap Packard Bell laptop, which my ex insisted was a really great buy but has in fact been beyond ***** right from the start. I'm getting a PC soon and it can't come soon enough :)
Got a new HP laptop a few months ago when my old tower system's hard drive started making funny clicking noises. There was a message on the screen that it needed booted or something-so I did and it's now lying in bits in the spare room!
