I was thinking about buying the new 13" macbook air (maybe uping to 4 gigs of ram). It's primarily going to be used in a small business. So, Basic tasks: office for mac, internetbrowsing, some movies (how does it handle 1080p?), pictures and light photoshop. The reason I'm considering it in the first place is because of portability. Is it worth the money? I'm afraid it's not going to be "futureproof" enough... Thanks in advance!
