Five USB ports? Apple have traditionally only included 3 USB ports on the back of the computer. OK, so they include 2 on the keyboard (Apple count this as 5 ports, cleverly omitting the point that you lose one by plugging the keyboard into the back of the Mac).

Looking at their site, they have done the same on their new generation iMacs (the display port ones) so why on earth would they include an extra two ports on their bottom of the range machine?
