We use the x220 & x230 in our office and while I don't use one as my main machine, I can answer some of them in case that commenter doesn't come back. 2. Graphics, Sleep wake, wireless, all yes. Not sure about the others listed but there is nothing that would cause a problem as a work machine. 3. Yes 4. Yes but not sure about display rotation. Displays attached to the laptop dock work as well (everyone at work uses one) including sleeping the laptop removing the laptop, and all the windows taking care of themselves. 6. Fine but its smaller than I'd like (spoiled by my air). 7. Solid but I'm not much of a keyboard snob. I can type just fine on my Sager's Mac knockoff chiclet keys or a cheap membrane keyboard. In terms of battery life, we seem to always have our machines plugged in but no one has ever complained about poor battery life.
