I recently hired a salesman, around 60 years old, for my company and learned that he doesn't have a computer at home. He will be traveling and presenting our products to different clients and needs a laptop to help him with his job. The laptop will mainly be used for quickbooks, microsoft office, and emailing; no heavy usage at all. I need to figure out what to buy his as a laptop. I don't know if I should go the netbook route, or buy a macbook. I myself have a MacBook Pro, but he definitely doesnt need the size or speed of that. Whatever laptop/netbook I buy for him needs to be very simple to use. Could I use a linux netbook for simple tasks like those listed above a la the dell mini 9, or 12? I am concerned that a 9 inch screen is too small for a beginner laptop user.
