Thanks for the suggestions! I actually dug into some of the reviews on Amazon and they don't recommend it for heavier gaming (e.g. First Person Shooters) because the keypress becomes "invalid" if held down for 10-20 seconds (e.g. I use the "c" key for crouching). Does anyone else have any other wireless gaming keyboard suggestions?
The Microsoft Arc aesthetically looks great. I have to admit that I didn't read the reviews because I'm currently using an old school Logitech MX 700. The MX 700 works really well, as long as the receiver is about 1-2 ft away from the mouse usage area. If anyone else wants to dig out their MX 700, it works well in Windows 7 except that you can't really change the advanced settings (e.g. higher refresh rates) because there is no driver support. I believe there are some workarounds but I have yet to try them.
