My daughter knocked my old Dell laptop off a table and it's been laid to rest, so I need a decent, inexpensive, (but reliable) laptop that I can take on the road with me a few times a year. Something sub-$500 would be ideal if possible. Lighter is better. I'm not up on laptop tech whatsoever, so if I could get a few reco's to look into, that would be swell. Happy New Years.
