I was in exactly the same dilemma.
Yes the MBPro is overpriced, but it is better than its mainstream competitor by a country mile.
I was so tired of the "boffin" Windoze formula I sought some clean air and found it in the MBPro. So far it's been a great experience (though I had done Mac in the past), I am just fortunate to be in a position at the moment to enjoy luxury over cost, and what a breath of fresh air it has been.
Of course if I were a tight @rse I would probably have stuck with Windoze as it's backwards compatibly with all my previous baggage, but I really wanted a change for the sake of it and MBPro delivered just that. It still has the very real potential to be used in "boffin" anger but I really couldn't give a rats. I do Unix/Linux in my sleep so with the power of VMWare/Fusion I still have all that "boffin" power at my fingertips anyway.
Yes it's pricier, but if you tire of Windoze like me, it's well worth it.
