Fran - you're fishin' with no bait. You know you want the Micro. You've got/had everything else. There are no real surprises with the Micro except for its size. It has all the pros and cons of a PA50 SD. If you prefer the i30 over a PA50 then go that way.
@ Ian - I think of the Micro as a thinkpad and very light dynamite arranger. The one thing the Micro does have me thinking about is switching my big board to a PA800. I don't think players will give up their bigger rigs for the Micro, but why sell it for, say $350 in a couple months? It's a damn good package.
Happy New Year to All!
