Yeah I got mine today today. I like the feel of it. I was a little intimidated because I have been using the logitech MX revo, but I like the size for maneuverability. Works fine without the drivers. As of right now, I am having the same issue running the razer configuration software using XP through parallels. For some reason it will not recognize that my mouse is connected to my virtual pc. I am curious to really see how long the batteries last on this bad boy. My first impression was excitement, but then disappointment that I spent $80 on this when I have a perfectly good and awesome mouse already, but I am starting to see the value in it. After taking a really quick look at the configuration software (cant use it yet), the feel of the mouse, and customization, and the extra goodies (carrying case and wired connection), I believe that this is worth the $80. The Kabuto pad is also very nice. I bought it with the discount and am happy, but I think it is worth it if you have that extra little bit of money. The comfort, quiteness, and feel of it work well with the Orochi. Solid mouse and good pad.
Also, if anyone has any tips and setting up my mouse properly in XP so I can edit macros and whatnot, please post here.
