okay i'm asking this for a friend... he's looking to upgrade his laptop... and is wondering if the MBA would be suffice power and what not for him... he would mainly be running iWork Numbers, Excel, and FileMaker Pro for some database and spreadsheet work and cruising the internet, email, etc. he's looking at getting a refurb MBA 2.13 GHz, 2GB RAM, 128BG SSD. his other option he's looking at is a refurb 15" macbook pro 2.66GHz, 4GB RAM, 320GB HD. just curious as to what some of you might suggest. thanks.
