I have never had a laptop before and I've always really wanted one. Recently I've been thinking about buying one but I don't know what optional equipment I need. It will mainly be used while on the road...away from home while at my new student rad tech job (work on homework), on vacation, out of town, etc. I would like to be able to access the internet while away ie directions, places to eat, shop, etc. I don't know anything about laptop batteries, chargers, etc. Can anyone help me with what equipment I would need to get started?
