I love my G13
-I put the g13 on the tray\arm with mouse ,with the g15 on the desk for more standard keys & non quick commands
-what I like is:
-second lcd ,1 for msi ab and 1 for core temps , I do not like osd
-keys are not offset per row -so s under w ,not off set
-the big thing for me is the thumb , I remap the mostly used functions\commands to the joy stick x4 and the two buttons beside it .that gives 6 buttons[+1=7 ,1 more on the main group of keys ,space bar] my thumb can easily hit without moving my fingers away from the wasd keys
-think about how easily it is to hit the space bar[with thumb] and think I can hit 7 keys [could be 8 but the center button is to hard to push straight down]with the same ease ,while still moving around or not taking my eyes off the screen , for the eg. i,o,p, buttons
-it's a pain to set up , as I play the game - figure out what keys are required - remap keys in a profile and after I just print it out ,remapping of the keys would have to be remembered on a key board any ways.
-not for everyone but I like it
