i was purchased my new PC in March 2008. After few month my keyboard was damaged. I would take my brother keyboard which is cordless. keyboard Name is Logitech EX90. when i was attached keyboad to the pc. i was surprised that keyboard and mouse no need any driver and software to run and all special keys was working fine. The keys was soft. the looks of the keyboard was very intractive(good). but there are one negitive point it cannot work on window 98. otherwise product was very good. After few days when i was given back the keyboard and mouse to my brother then i feel sad. because now i was again wired keyboard. cordless keyboard required 2 x AA batteries each device either keyboard or mouse. the life of batteries is very good in keyboard but in mouse is good.
Keyboard battery life is appox is 1-1.5 years
mouse battery life is appox is 4-6 months
Now i am planning to purchase the EX90keyboard in few days. i think better than wired keyboard. because it is little expensive than wired keyboard.
Thanks you
