My largest beef with the 1200 is the lack of hard buttons for "colors." More and more products use these - mostly OEM DVRs, but Tivo uses them too. For heavy TV users, it's annoying not having hard buttons for the colors.

I bought a 1200 because I wanted the big touchscreen, and I completely missed that it was lacking the color buttons. If I could easily do it again, I would go for an 890 instead.  (Mine was bought from someone on eBay who had just received it back from RMA and was switching to RTI, so it's effectively a new 1200 but without any dealer behind it anymore.)
