I bought this because I found it difficult to touch-type quickly and accurately with my previous one, because of the feel of the keys. This Cherry keyboard is a welcome improvement, a bit harder and clickier. It looks nice in charcoal and black, classier than just plain black. It has no shiny surfaces to collect fingerprints (apart from a tiny bit on the mouse). I like the fact that the alphabet keys are marked in the traditional way, in the top left corner, rather than the recent fashion of putting the markings in the middle--why are we so good at unlearning past wisdom!
The extra function keys for media control, internet and mail work well and the whole thing just installed itself (Windows 7) without any need for software. My setup is only about 4 feet away from the receiver; nevertheless wireless reception has been faultless. It's too early to tell about battery life, but the current consumption figures given are comparable with my previous one. One thing I often see on reviews of wireless keyboards is that 'there is no LED for caps lock.' Well, there's a reason for this--it would drain the batteries. However, in all versions of Windows since XP at least, there is an option to bleep on caps lock (hi-bleep=on, lo-bleep=off). I can't remember how you turn this feature on, but just Google "caps lock bleep" and I'm sure you'll find how to do it. I somehow managed to turn it on, and it works just fine.
The mouse is a simple scroll wheel type, but it looks good and works well. At first I thought it looked a bit flat, but now I really prefer it.
A worthwhile improvement on my previous desktop. Be careful to order the JD-0500GB (UK keyboard layout) as you'll find international sellers who are offering other versions.
