Do you use wireless mouse? If yes which brand?

i use mi you can get it at wal-mart i had it for over a year it's been a good set keyboard & mouses

I use logitech. There are 2 types of optical mouse. The original optical mouse and the optical LASER mouse. They differ in beam frequency and reaction time. The laser mouse is much faster to react and it has a stronger beam. Some optical mouse may have as many as 6 beams on them. The more beams the more accurate and responsive the mouse is. Normally, there's only 1 beam for the optical mouse and some have 2.

no but will soon buy one.. am planning to go for apple.

if you used them for gaming, you shouldn`t use wireless keyboard. I had a wireless keyboard and doesn`t work at games as i wish i recommend you the Logitech
