best inexpensive laptop for graphic design?

hey guys, a friend of mine asked me this and i'm really not sure what to tell him. personally i do graphic design and have always used macs. he is looking for a non mac because he just wants to build his portfolio and hopefully get into the school hes trying to get into, which will provide him with a mac. so he's just looking for an inexpensive laptop that will get the job done in the meantime. thanks!
