As a developer i don't see any particular reason for using exclusively macs for personal computing, a linux box/laptop should be good enough (never owned a mac). But if someone really care about mobility, buying a mac (air?) could be a good idea (personally, i'm waiting for the next generation air, hoping for faster processors).
