Well... I have one of this and I am quite enjoy it due to the fact that they are wireless. However, there are 2 things that I don't like about. First, they use battery and I only use for a couple of days and they are almost gone now. Second, I have a dual boot in my machine and my BIOS now doesn't support USB in DOS mode. I am using ABIT VP6 and if anyone know there is an update for that, please let me know. Thanks!
