>>12264While that second pic is super minimalistic, it pains me to see such a drop in productivity with 1 screen and no real mouse. Balance between full-on desktop and nearly nothing is needed, so I'd go with that first pic.
Also, if that's going to be placed with any permanence, I suggest getting a docking station. Allows for DVI out, more USB ports, and headphone/speaker out all at the back, for neater cables. Totally worth the $20 it cost for mine.
I have a similar setup, waiting for things to come from kalyx before posting.
