Been thinking of getting one myself.
There's a website I found selling two macbook pro's, one 15.4" the other 17" screen. The 15.4" is £100 cheaper than rrp and the 17" is £200 cheaper, plus they give you a 300GB external HDD and an ipod nano (depending on availability, else it could be a shuffle).
Don't know if there any good though, maybe someone else knows who I'm talking about.
Don't think I'd be able to link to them, as they also sell other notebook/laptops.
