I've been wondering the same thing about the spider amp and Mk11 shortboard. Nice that there are so many pre-sets to play with, but putting a laptop up on stage a) kills the volume control via pedal, and b) is a fairly bulky and expensive way to 'tweak' your sound on the fly (impossible via front panel knobs-they're TOO sensitive and the unexpected could be disasterous). I know you can program the pedal board, so isolating the volume control shouldn't really be a problem, but bringing up a heads up display of all the effects on the preset channel would be excellent if it could be done on a tablet on the mic stand, as opposed to a computer somewhere near another piece of equipment (or beer) that might 'affect' it's performance.
