The smart control is getting dangerously close to my perfect remote control. A simple remote control (something less than the 1 billion buttons found on most french bread-sized universal Remotes) that is still fully programmable with tactile buttons. My smart phone will never replace my remote because I don't want to have to look at my remote to use it.
Counting the directional pad as 5 buttons, I only use 14 buttons to control all my equipment and media for my HTPC based setup. I wish I had the chops and contacts to do a programmable remote kickstarter. I think the world would be ready for a learning remote version of the roku remote for the HTPC crowd.
