I haven't had much need to look at the MS Surface tablets, because I've got my iPad for everything I'd use a tablet for, and "real computers" for everything else. However, over the last couple of months, two of my friends picked up Surface Pro's and both are gushing about them, and how useful it is to have a "real computer" in a tablet form. Both of these guys are primarily Apple fans (one is a confirmed MS hater). Remember the Surface Pro is not the same as Surface RT, it's more like the equivalent of having an iPad that can run either iOS or OS X on the same tablet, albeit at the speed of a Mac Book Pro! Meaning use a real mouse/keyboard/monitor with it if you want, otherwise use it like a tablet.
Then I saw this vid, and realized what a nice solution this might be for someone that was highly dependent on Maschine workflow and/or wants to use it like a standalone piece of gear. Not where I personally am headed with Maschine, but a nice setup for some:
