My sister went into the apple shop in Milton Keynes sales guy asked what she wanted she needs something very small that must run photoshop so she wants the Air as the size and cost are a lot lower than the rest. Sales told her it will be no good and will not even run the program told her to get a Macbook Pro sounds like a sell out, anybody out there run Photoshop with the Macbook Air i cant see no problems with it may do with a mem upgrade thats all.

I run PS all the time on my MBA and it works fine. But I'm usually doing either web design or photo editing. If she's doing huge print pieces, then maybe it wouldn't be the best choice, although the MBA would certainly do the job. She can always get a small, fast, external USB hard drive for work related stuff if she really wants the MBA.
