Beth, I do not like wireless keyboards, mikes nor speakers, so I'm afraid I
cannot address them. I use wireless routing in my place and everything has
a wireless card, including the laser printer. The battery life in the
Fujitsu, if that is what you were asking about, is about 8 hours of intense
use. There is a hot swap bay where you can put in a spare battery or a
cd/dvd drive, a nice touch.
I have discovered that computers are alive and if you speak kindly to them and show them pictures of computers of the opposite sex, they behave better.
