Sadly I can't get too interested in a machine like this. What I want in a work machine is the following:

1) 16GB RAM (or more) 2) High density display 3) SSD drive 4) Quad core or better CPU 5) Small and thin 6) Discrete NVIDIA GPU (not the Intel integrated crap)

Apple's MBP is the only machine I know of that fits this bill. I'm becoming less and less a fan of OSX, but you can't argue against the hardware. Can anyone point me to a non-Apple machine that does these things?

EDIT:

Thanks for the pointers! I'll look into the Dell and Lenovo machines mentioned here. It's been a year or so since I've looked for machines comparable to my older MBP, so it's cool to see some new options.
