Hello and welcome to Tom's Hardware Forums.
A lot of pepole in the creative businesses seem to prefer Apple Macs so go to the Apple store and take your pick form their Powerbook range. It will cost a lot more but last a lot longer, be easier to use, have cheaper and more easily upgradeable Operating Systems but will fit in with all the other architects and students you're likely to meet.
Sorry - they call them Airbooks now http://www.apple.com/macbookair/
