“Easy” and “enjoyable” are different things. The Roku UI is extremely slow/jittery (even on the fastest models) and the layout of their software keyboard, in combination with the design of their remote (and/or smart TV remotes), makes entering text take an eternity as well. (And their voice support isn’t good enough to rely on in place of it.)

When a Roku is just sitting there doing its thing, it’s fine; but when you have to get it to do something else, it’s like a line at the DMV.

I think they might have meant "crap to develop for"?
