Hi all, I'm about to replace my old MBP and as I travel a lot and fancy a treat, I'm planning on a MBA as the replacement. My question is whether the 11" MBA is big enough for someone who does fair amount of word processing, film watching and web surfing. The benefits being that it's more compact (obviously) and I can load it up with more of the extras. If the opinion is that I should definitely get the 13", I'll do so, but it may be the basic MBA. Thanks for any advice!
