I purchase this keyboard as a replacement for my Microsoft Natural 4000 , which die after a unfortunate incident with a ill-placed coffee cup . all i can say be , I really like the g110 I buy to replace it . the g110 introduce a lot of incremental improvement to keyboard design that make it a joy to work on . key Feel : the first thing I notice be that the response from the key be just about perfect . the key have just the right mix of travel and spring to they . as a frame of reference , my first keyboard be one of the old IBM clunk-o-tron , which give I a tendency to type somewhat harder than I probably should sometimes . I have be experiment with different style of key to find something that would not leave I nurse my wrist with ice pack at the end of a busy day . laptop-styled , low-profile keyboard generally do not have enough travel for comfort . the Microsoft Natural 4000 I have be use be acceptable , but the key feel a little squishier than I would have like . key position : the ctrl and alt key be big enough that you will not find yourself accidentally hit anything you do not intend to , which be a frequent annoyance for I on other keyboard . function key : it take a little while to get a sense for what I could use the function key for , but after a little while I find set they up to handle shortcut in my ide that I use regularly I find myself surprise at how happy I be to save my finger from the need to awkwardly position themselves across three key at once . the only issue I have have with they so far be that I find myself hit g1 instead of esc for the first week I have the keyboard . back light : the key glow . the back light be not terribly bright , but in the dark there be enough light to get you hand position again if you find the need to stroke you chin thoughtfully at any point . volume Rocker : this be a neat feature , and be much more comfortable to use than traditional volume adjustment button on other keyboard I have use .
