Caveat: I am not a gamer. I bought this keyboard on a quest for something better than the mediocre, mushy-feeling, gimmicky keyboards that have lots of features but which fall short on the fundamental purpose of keyboard -- typing.
The first thing you notice about this keyboard is that it is big. Really big. It measures 21.5" from side to side. I was so concerned about this keyboard taking over my limited desk space that I almost put it back in the shipping carton unopened. That would have been a mistake -- this is a fabulous keyboard, especially for those of us who grew up on the original IBM PC/XT, and AT keyboards.
No, it doesn't have the clicky sound of the original IBM boards, but the layout is nearly perfect and the feel is excellent.
I had been using a Logitech MX3000 keyboard, which met an untimely death by coffee. I was happy enough with the MX3000, and I almost bought a 3200 to replace it. But I didn't really need a cordless keyboard, and I never really cared for the mouse that comes with the Logitech 3xxx cordless desktop sets. Now that I have them side-by-side, there is no comparison. The G11 feels solid without being stiff; the MX3000 feels mushy and imprecise. The F-keys on the G11 are full-sized and are located where my fingers think they ought to be!
The provided keyboard profiler software is unobtrusive and easy to install. I have found the "G" keys handy for storing passwords, my e-mail signature, and other short snippets of text. The backlighting feature is more useful than I imagined. I don't miss the extra buttons on my MX3000; the G11's volume control and media buttons cover about 99% of my needs. I would have liked a standby button, but I can understand why you wouldn't want one on a gaming keyboard.
$69 is a lot of $$$ for a keyboard. But if you spend most of your days typing, it is money well spent!
