those dials mapped to scroll bars would be super handy for hansoft. :) i'm dissapointed to see that the dials are made from plastic tho, doesn't seem to fit the rest of the hipster bait style they got going. wake me up when they do the ivory edition.
I'm more interested in the software letting it work for things like photoshop. For music I use one of these which are cheap as hell and work fine http://www.korg.com/services/products/nanoseries2/NanoKONTROL2_black_MAIN.png
hardware controls like this are cool in theory but i dont use them much. for things like knobs on midi keyboards i had one that had 20 knobs /sliders /pads. i ended up using the software sliders a lot more and automating them
