Almost a year ago Steel series, a popular Asian brand for input devices released their answer to MMO players for the utter lack of mice with intelligent button placement and customizable buttons through software.
It sounded good on paper, but when it was released it was an absolute failure, the software was buggy, the build quality is terrible, and the software is not compatible with 64-bit operating systems which is what I use.
Well at any rate it looks like at least one of the major gaming input device companies finally has a clue, Razor just announced the Razer naga.
Here is a youtube video highlighting it's features:
