I'm looking to get my 75-year old mother a laptop. She's not doing much but surfing around, doing facebook and looking at photos. Probably at 15" monitor will do. I love momma but I need to set this thing up in such as way she's not calling me five times a day. As a mac guy, I didn't know if I should go used or new and where I might find a pc for a reasonable price. I'm guessing the budget is $200-250, if possible.
