This logitech is awesome. So slim. So responsive. The buttons are so thin (like a laptop), so you don't have to press them very far to get them to register. I haven't had a chance to try out the others yet, but... this one's awesome.
Though I usually hate media keys, these are uber-tiny and work without any additional software, which is pretty slick. Probably won't use them though.
My only complaint is that it's so flat. I'm used to having my keyboard up at more of an angle (I always drop the legs down). The legs on this one only lift it up like 1/4 inch from horizontal, heh. But, man, it's so slim... Matches my monitor and mouse nicely, too.
I think I'll bring the split one to work. As for the other two... backups, I guess. I could hook one up to my laptop, maybe, and one on my second computer so I don't have to use the KVM to switch to it all the time. Can't wait to try this out gaming, so you might actually see my playing tonight. And I'll most certainly be playing
tomorrow night.
