from my exp as a WOW gamer, i find that G15 is kinda good in the sense that it will display all my stats in the lcd screen and the program is implemented by Blizzard itself. the Gkeys are very good too .. cos it can store keystrokes which i find quiet useful.

The only draw back i can find with the G15 is the quality and the space in between keys. the quality of logitech is kinda questionable.

i own a G7 mouse.. and i goto say it is a shitty mouse and razer have better quality mouse.

after that i bought myself a apple keyboard just because the keys are closely packed together and the feel is so nice.
