I need a simple word processor, spreadsheet, internet, note-taker for school. I have a new MacBook... but I'm a little worried about bringing it with me around campus. Accidents happen, and in my current financial situation, it would be a great loss. Besides, I do not need all that power for taking notes or working on a paper. So I was thinking... a clamshell, with a Hardrive upgrade (let's say 40GB), a new battery, and the wireless card built in.... would that be a good option? So where to buy and what is a good deal vs a bad deal? How much is a good deal on a decent clamshell? How much is a decent clamshell with an up'ed HD and the wireless? and how much is a pricetag new battery? So in other words, what would you expect to pay? Also, what do I look for to find a good deal? I'm using e-bay and I'm just a bit worried about being ripped off... I know NOTHING about clamshells, since I joined the Apple crowd a year ago with this MacBook right here. Thus, people who sell, own or did own clamshells... please help. Also, this is my first post here on MacRumors... so Hi everyone!
