Do wireless keyboards and mouses suck?

I've heard people complain about wireless keyboards and mouses. But they seem cool. What do you think about them? Get them or not?

I had a mouse.
IT sucked.
The thing never worked,it had to be a certain distance from the port for it to work,
and id hafta reset it constantly.
plus the batteries die like instantly.

I wouldnt recommend it,unless you get one of the more advanced ones
=]

yeah, unless you get one of those super expensive mice, it's completely worthless.

yes they arel cool unitl the batteries wear out!

I think the idea is great, but you would need a good quality one, and I've never felt the need not to have cables, if I have cables, I don't need to worry about batteries, and its always attached to the computer, and therefore harder to lose

I have both and LOVE them. Yes you have to replace the mouse batteries every couple of months but the keyboard has gone a year without changing. If I want to use my desk space, wireless let me move my keyboard totally out of the way instantly. I can also use the keyboard across the room. I raise my monitor up on a Fellowes monitor stand so I just put the receiver under the stand out of the way. And with the mouse there is no damn cord getting in the way.
I can imagine where a corded mouse might be better (e.g. young kids around that might walk off with it) but in my kiddie free house its never been farther than a foot from the same spot.
Also I do not have WiFi so if that caused problems with interference, ... I don't know what I'd do in that case. Maybe not use WiFi???
