Finally, I'm getting my laptop, which I've desperately needed for the past years (this POS Dell ain't cuttin' it). I've checked out the brand new MBP, been following them since the leaked photos, saw the launch, etc. But considering the Live.com discount, and the previous generation being cheaper, what's a better buy? My budget is about ~$1700. So, is it the previous 2.5 with the 512 video card, or the new, base MBP?
