I've had a PS3 for about a year and a half and opted for the prole friendly 80 GB option. I have yet to make a significant dent in the allotted space.
I say opt for a little more work and locate a used 60 gb one for hardware emulated backwards compat on 80% of ps2 library. Its harder, but in most cases will cost about the same, does more and as the guy above mentioned its hard to really really use that much space. Extra HD space is kinda irrelevant when you can A: exist on smaller hard drive and B: if push came to shove you could change out the drive size on your own.
EDIT: Personally I wont buy a new PS3 until they restore ps2 backwards compatibility in the slim model, there is no excuse for it to not be present now that the technology has progressed a step.
Beyond that if your hell bent on buying new.. save yourself the money. Extra HD space you wont likely use would buy you a new game.
