which kyeboard is better WIRED or WIRELESS ???

it's better to use a wired one.

wired.I don't want to waste time changing batteries.

Wireless I mean that is the need of tghe hour wireless keyboards,wirelss mouse and so on

I've always had a wired cheap keyboard. But from some month I have a new Logitech wireless keyboard. It's a kit keyboard+mouse optical and wireless. It's like a wired one, battery lasts very much in keyboard and it's very cool. Anyway I use rechargable batteries. I like very much added buttons, key function and software by logitech. I am not so satisfied with logitech mouse of this kit because batteries lasts only 1 month (rechargable 2400mAH). I like it wireless because when I must unmount my system and clean it or do something, i have less wires around

i am using wired keyboard at the moment but i think wireless keyboard is more compartable and better than wired...

I use a cheap Wired keyboard. I don't want to buy a wireless one because I will have to buy batteries.
