at first i thought id pretty much wasted money on this over a standard 101 keyboard. then after a while i started utilizing the keys a little bit more.. asigning difficult keystrokes that i normally wouldnt use to the extra keys (ctrl+alt+a, etc).. which is handy. then i started testing with the macro ability a bit..

in shadowbane i run 10 characters of different classes. bards chant mana regeneration and resist songs and group dispel.. druids earthquake, group heal.. etc.. binding separate keys and functions for every class individually would be horrible. running multiple macros would be horrible. with the G15 i can press a single button and it automates every single keypress. i can simple press it when i want to start casting and then press it again when i want it to stop. its so simple i can run an entire group with almost no effort.
