Pretty interesting. Part of me thinks if this was around even 2 years ago, when I was way more actively involved in photography day to day than I am today, I'd have jumped on this. OTOH, I only did and do pretty basic editing in Lightroom - it's mostly just my raw processor and I then export to one of the Nik plug-ins to do most of the edits. Assuming this deck only works with the Lightroom controls and not those of various other programs and plug-ins, it wouldn't have much utility for me. But it's a cool idea and will be interesting to see where it goes...
