Call me old school -- and you'd be correct -- but for all those reasons above, I don't ever see myself playing virtual instruments from a computer as I really enjoy having a purpose-built keyboard in front of me.
To me, I find there's a very strong mental connection to the board as well (tradition, history, reliving past gigs, old songs or sounds to emulate, pride of ownership, etc.), besides all the physical aspects of the keys, knobs, and sliders, etc.
Plus, after 9 to 11 hours spent on a work computer every day, the very LAST thing I want to do is to start up yet another computer................... Ugh...
