Logitech and efo keyboard - which one is better?

[jonejone]

Logitech diNovo Mini is so well known and most people know its features. Recently, I have surfed through some forums and think that this efo wireless handheld keyboard is quite good. It is newly developed for car-pc, HTPC, IPTV and PC, etc. Please comment which one is better
