Tell me something ....
I'm a cordless device hater. The 2 times I purchased wireless devices, the batteries ran out in 2 weeks, every time.
What would you say is the maximal battery life of your keyboard and mice?
I owned a Logitech Cordless Internet Keyboard and a Matching Optical Mouse and they sucked bigtime. I'd rather stick with USB any day. Before the Logitech, I owned a little slim wireless keyboard, and the batteries on that thing died in maybe 2 weeks and some days.
But just for info....I want to know. And what is your usage pattern like? About 3-12 hours a day? Gaming, Productivity, School? Etc. Etc.
