I get reimbursed up to a hundred dollars from work for electronics (I'm on the yearbook committee at my school), and this weekend is free of sales tax in Georgia (woohoo) on any computer gear (and school clothes and supplies for any of you who live in or near the state).
Anyway, I need an external harddrive that is USB so I can simply run from one computer to the next.
I want the most Gigs (or possibly terabytes) for the money. I don't need it to fit in a shirt pocket. Big is fine.
I'll be literally storing thousands of photos of students and will need to bring it back and forth from work for editing.
