I have exceptionally large hands and I find using a normal keyboard difficult. This my second purchase of this style of keyboard from Microsoft the first one lasted ten years. This new keyboard is as easy to use as its predecessor, but the improvements and additions are unbelievable and too numerous...

This keyboard was definitely designed around ergonomic ideals. Microsoft has taken a well-tested split "Natural" keyboard design and ergonomically improved it even more for the heavy user in mind.

Split keys: you either love them or hate them. The ergonomic design, built to reduce RSI and enhance your comfort, can take some time to get used to, but after going through a month of irritation relearning to type, a lot of people never go back from Microsoft's Natural Ergonomic Keyboard 4000.

First and foremost among this keyboard's features is an ergonomic design meant to promote hand and wrist health during use. Anyone who spends numerous hours each day at a computer will quickly appreciate its comfortable shape.

You can find much cheaper ergonomic boards than the 4000 but none with the same great design or interesting additions. It looks nice, and – most importantly - is extremely comfortable to use. Well worth shelling out for.

The wrist rest is literally built onto the keyboard and is not removable, but there's nothing to complain about it. Why? Its Leatherette cushioning is friggin' comfortable, by far the best wrist rest I've laid palms on.

This keyboard seems to keep going up in price, but periodically goes on sale. Wait for a discount and get one. I have 2 and haven't had any problems with the space bar. One con is that I found out that this USB keyboard is not compatible with a PS/2 adapter, which now makes my KVM switch useless.

I've owned 4 of these Microsoft 4000 Ergonomic Keyboards now. I love the keyboard, that's why I bought 4 but they are somewhat problematic (or at least they can be). The first 3 I bought each had the same problem.

Great features and easy to setup especially with the unreliablility of VISTA. Office users are happy and have switched from conventional keyboards to ergo keyboards.

I've used microsoft's earlier version of this keyboard years ago. Between then and now I've used an assortment of keyboards. Several months ago I started using this at the office to make typing more comfortable. It has a negative slope design with the keys at an outward angle.
