Well I guess I didn't mean slow, I meant you can see widget flicker
like there's no double buffering for widget drawing. I find the UI
clunky though -- like you can feel the gears turning in the
background. Hence I'm not surprised that channel changes take a long
time given this clunky feel. My point was is that it's no XBMC in the
frontend department.
