This is too irresistible not to upgrade. I'm more interested in CPU/Memory and the Graphic card bump is only $100. In total, it should cost $3.900 excluding taxes (or $2.500 if I "trade in" my current machine). Looking at the competition, a ThinkPad P53 Mobile Workstation with the 2.3Ghz processor / 32GB of RAM will cost $3.759.
I think the pricing is very competitive, given that the ThinkPad is a giant box. So even if Lenovo lowers its price in the next iteration of its ThinkPad, the MacbookPro will quite match up.
Kudos for Apple for doing this!
