After years of proclaiming wireless ain't good enough for real gaming mice, Razer's got a Bluetooth notebook mouse. Otherwise, Orochi is what'd you expect from Razer for $80: 4000dpi, 7 programmable buttons, and onboard memory for storing your macros.
If you still don't trust wireless or your batteries die, it has a breakaway USB cable—though Razer claims 1-3 months of juice under "normal usage." What exactly is normal usage, you ask? I don't know. [Razer]
