I have the same sort of problem, and went with the MBPr. I need large VMs (6gb+ of ram) and travel a fair bit, so dragging around a big Dell was taking its toll. The MBPr has been great, the only limit being disk space, 512GB fill up quickly when each Windows image takes 40+ GBs. Also, the gorgeous screen, 6 months later, is now ghosting on me.

A colleague went with Air + VPN to his home lab, but that fails when your customer works "in a bunker" (i.e. heavy-handed firewalls and proxies, common in financial sectors).

Take your MacBook in and you'll get a replacement one, typically on the spot. I know at least 3 people who've had their rMBP replaced due to ghosting.

Just to reiterate this - I had the exact same problem, and they replaced the display immediately.
