I just receive the new k800 illuminate cordless keyboard from Logitech and so far I really like it . my husband and I have a wall unit with two computer and each of we area be separate by a desktop . my corner be fairly dark even in the middle of the day so I want a keyboard that light up , but all the one I know of be cord , which would not work without some sort of extension . then I find this one . so far I enjoy it . the lighting be automatically as well as manually adjustable , it can recharge on the fly just like Logitech 's newer mouse with the usb charger -lrb- which will work great with the usb port in my monitor -rrb- , and the key stroke be smooth and fairly sensitive . the key feel slightly larger than my previous keyboard -lrb- a mx5500 -rrb- and I know the f key be -lrb- the tiny f key slightly annoy I on my other keyboard -rrb- . there be a slight curve to the thin keyboard to make it slightly ergonomic . all in all I be quite pleased . now it be just to see how well it hold up - my job be datum entry from home so it will get a gruel workout ; -rrb-
