I sprung for the 32. Probably could have been satisfied with a 16-- but when it comes to matters of technology, I tend to buy more than what I need when I need it to stave off obsolescence.

The MBP I bought in January of 2007 is a BTO 2.33 GhZ machine with 4 gigs of ram. At the time, it was pretty much state of the art. As of today-- quite a lot of time by tech standards-- the MBPs start out at 2.53 GhZ with 4 gigs of ram. Yeah, I know the video capabilities have improved significantly, but in many ways, my machine is still relatively current. It certainly is current enough for me!

In the end, it's a matter of priorities. Everyone has to ask themselves just how susceptible they are to tech lust-- and how that lust fits into their actual needs. A lot of people on this forum go absolutely nuts when Apple releases the latest and greatest (I'm often times among them). But the tech race is not winnable by those that don't make absurd sums of money.

Suddenly the lyric by Cheryl Crow comes to mind:

"It's not having what you want
It's wanting what you've got"
