no problem pair with laptop run on Windows Vista . curved ergonomic keypad be really comfortable for long use , and the individual key layout be friendlier than full size wave keyboard . the battery life seem to be reasonable , no replacement so far after 1 month usage . take about 3-5 seconds to wake up from battery saving mode . ca not tell if Cap Lock or Num Lock be on or off ; a status indication led at the keyboard would be helpful . this can become irritating , especially typing a password text box . chassis for the keyboard could use stiffer plastic material , feel too fragile ; I doubt this keyboard can last long .
