OK I had a Unibody that arrived with a dent to it's been sent back to Apple UK. It was a refurb anyway so they've refunded £799 to my card. Now I could buy another for the same money or get the poly new for £676 (using Apple Edu Discount). I really liked macbook unibody with the exception of the aluminum battery compartment cover. With the poly the lesser Hard Disk and Non LED backlit don't really bother me, but as I've not owned a poly macbook before two things are bothering me... No 1 - Does the white plastic discolour and can it be cleaned? No 2 - The 9400M is a cool bit of kit but what bottleneck is created by using DDR2 SDRAM instead of DDR3 when playing 3D games? Any advice will be greatly appreciated before I split with my money again.
