It was nice for things like switching HDMI inputs; you could dynamically update the name and icon, making it more intuitive for someone who had never used the TV before and didn't know what was plugged into which port. You could also adjust settings more easily without everyone have to watch together with you on the big screen as you dug to find the obscure setting to tweak.
But your complaints were equally valid, and were a concern at the time.
I would have liked to see it ship, if just to see if customers liked it. A traditional remote still worked too. But oh well.
