[Jack Rabbit]

A cheap laptop is a cheap laptop. I doubt it matters much what you get as they are all about the same. Take a tour of the shops that have demos and try them and pick the one that suits your fancy.

The two most important things I would suggest you look at are screen and keyboard. A cheap laptop will lag in performance but it sounds like your friend is just going to do office stuff so that will not matter. Check the keyboard to make sure it is comfortable to type on and the keys are in a good place. Check the screen to make sure it is easy on the eyes in the conditions your friend will use it. If your friend wants to use it in the middle of a park then your friend will need a bright one. If it will be used in a dim lecture hall then you really need to find one that is not too bright.

If you are going to shop the big box stores look for the ones that offer a satisfaction guaranteed no questions return policy. They are almost always legit so long as you keep the box and stuff; just make sure you read the agreement and follow it. The last time I checked the Sony Store offered one. A guy I used to know used to "rent" cameras from them all the time. I think that is immoral and I do not suggest it but if you legitimately buy the unit because you think it will suit your needs it is good to have a fall back in case something bites you.
