Topic trackball: As my experiences are different. Either he does / not at all or normally responds without delay.
MENU and INFO button. The missing actually. For menu but there is a shortcut: simultaneously pressing the Ctrl and M keys
For INFO unfortunately not working.
The virtual keyboard on the TV is annoying. But for that the keyboard can not.
Alternatives to keyboard I can not really recommend:
The "TechniControl Plus" has problems with the reliability of the buttons on the directional pad. Until the purchase of keyboard I always thought the TV was a little sluggish. No, the TV is not it!
An alternative keyboard there is, well, not really: I've even tried it with the K400r. Alone the lack WWW button forces the use of keyboard and remote control. This is too cumbersome.
Final verdict:
A good approach. Very good for surfing the net. But as a remote control replacement not thought through.
