New web dev on the block choices

[DragonWoLf]

So I'm going to take the plunge now or soon enough now was wondering for a new web developer/designer would a 13"MBA be fine as I'd be using BBEdit and browsers mostly (not touching Dreamweaver) or would I need the 15" of a MBP?

I was just worried about the screen size, I guess I would need to play with them for abit at the store
