Insane or not the optimus, with each key potentially programmable macro + image it has the ability to be the ultimate designer/developer tool but at that price ill stick with my G15 not many around and places that still have them i saw one for AU$75 at "GAME" snap-ed it up too handy to have a spare but also the Cherry MX series key-switch (Mechanical switch keys) in the Gigabyte GK-K8000 makes it quite appealing and at roughly $110 all its missing is the display from the g15 and it would be bonza

there are some really sweet Keyboards out there i own 2 original blue G15's its the ultimate for work and play with all my tool presets for adobe mapped for work then there's simple chat command lines for team fortress 2 that makes it great it really shines at night like now this message is being posted in the dark :P

POO POO THE NEW G15 IS LIKE A DIRTY RASH! TINY DISPLAY 1/3 OF THE MACRO BUTTONS

the next best in my opinion is the Saitek Cyborg is next best sturdy built an all

and if space is a problem the stylish DKTBoard from Everglide is really comfortable to use its a little harder to get then the saitek but its supposed to be a little cheaper
