I've been researching laptops lately, siince I plan to buy one in the new year. My requirements are somewhat different to your friend's though, since my priorities are Linux compatibility and raw power (even though I admit I barely need it beyond running compiz=-)

Anyway...
I quite like the look of the Dells. I know they had a period of bad build quality and poor service for a few years, but my understanding is that they've improved vastly on this front of late: Nice machines, decent prices, good (well, good for a laptop manufacturer anyway) green credentials and Linux friendliness. That's almost certainly what I'll be getting.

I would avoid Sony, I have one now. Too expensive for the spec you get, and not overly sturdy.

My experience with Toshibas has been positive, but the last one I had was a long time ago, so things may have changed since. Lenovos have a reputation for toughness. HPs look quite nice, one of my colleagues has one. To be honest, If you're not looking for top performance, I don't think you can really go wrong with any of the major brands, and most of the lesser brands will do you well enough. A lot of it comes down to what badge you want on the lid.

Have you looked at the ASUS EEE machines? They are cheap, low spec machines selling for about half the price of a regular laptop. Screens are a little small, otherwise I'd be getting one of these. Might be just right for your friend's mother though.
