fayainz - The G13 works like a charm, I lurve it. I use it for almost all my games.
I really like it for FPS's, I enjoy having it to the left of my keyboard and makes playing more comfortable. Its also very sturdy so its doesn't move around like my G15 does in intense battles.
Its obviously also great for RPG's, MMO's etc. You can map tons of keys and create loads of macros. I have a number of macros I use in different games. Like in COD4, if I TK a teamie I have a macro that says 'Sorry' without me having to type a thing in.
The LCD is decent, you can get a range of different info, PC temps, performance, FPS etc. You can also change the colour of the LCD backlight unlike the G15.
Umm ya thats about it, what else you wanna know?
