The Microsoft Natural Keyboard is unique for the following reasons:
It is split into two, parts, so that your shoulders are not cramped. The keyboard is designed to accommodate the natural slope of your hands. To test this, hold your hands in a natural typing position and you will notice that your little finger falls lower than the index or middle one.
The keys are arranged at an angle. The ones in the middle are lower down and they radiate outwards. This serves a very important purpose. When you type on a normal keyboard, your wrists tend to angle outwards. This puts a lot of stress on the outer side of your wrist and the natural keyboard helps minimize just that.
Mice: So you have read the latest review on the 
latest mouse in the market, and it says ‘ergonomic this, ergonomic that’. Impressed, you are a II set to buy it. My advice? Be skeptical. The best thing is to try out the mouse before actually buying it. More often than not, the so-called ergonomic mice are either too large or too small. Many just don’t feel right. Most of these are made as per international standards and if you have small hands, you are heading for trouble.
Keyboards: Like me, if you type a lot, you have to be very careful while choosing the keyboard.
While the best keyboards are the natural keyboards (such as the Microsoft Natural Keyboard), they are very expensive (the one mentioned comes for a whopping $ 75 +) and so are avoided by most computer users.
There are a lot of fancy keyboards available at DataHand and other manufacturers. These keyboards can cost up to $ 1300 and above. You will notice that some of these keyboards don’t even look like the keyboards.

What’s the table height? Importantto consider, but this is relative to your chair. Make sure that when you sit pretty on your chair, the top of the monitor is at or below eye level and your elbows form a 90 degree angle when you lay your hands on the keyboard. 
How much leg space? A lot of ta bles that I have come across have several shelves (to place your CPU, UPS, etc). While most of us end up placing the usual junk there, ask yourself where you can keep your legs. When you are working on one of those long computing sessions, you need to stretch them!
Undoubtedly, the workstation has evolved from the days of the good old typewriter. Any P.T. instructor will tell you that you need to sit up straight and keep your back as straight as possible, not to rest it on the backrest and to keep your shoulders stiff. This posture was ideal for short bouts of keyboarding, but with the pressures of modern day offices, one often works for long hours at ago.

Where should your printer be placed? I would not recommend placing it on a lower shelf, in order to avoid injury to your back.
The mouse. I 
would say that this is the single most important thing to consider. Most workstations are constructed (to save on material) with a short keyboard tray that will accommodate not more than the length of the keyboard. This in turn forces you to place you r mouse on the desk. If your mouse and keyboard are not at the same level, it results in an ergonomic disaster!
You need to have the mouse right next to the keyboard, on the immediate right/left depending on which hand you use.This can save your shoulders a lot of trauma. While working on that Word file or chatting with someone on MSN, you suddenly need to click something on your desktop, so you reach for your mouse. If you are doing both tasks at the same time, you are causing immense damage to your shoulder because you are moving your entire arm all the way!

The problem starts with your computer table. Askyourselfa few questions.
How high is the monitor? Do you have to look up, or is it at eye level, or do you look down? Until a while back, the concept was to have the top of the monitor at eye level. 
With evolving designs and concepts this has changed to having the monitor at a lower level. I would say that the best thing is whatever keeps you comfortable. Remem ber to keep the monitor at approximately arm’s length. I have seen some neat computer tables in furniture shops, where the monitor sits on an incline. The initial impression is a little unnerving-you feel that the monitor is going to slide into your lap, but yes, that is what I would recommend as a good computer table.
How large? A measly-sized workstation is not for me. The reason being that in no time at all, you are going to share your table with stationery, files, CDs, and magazines. Make sure that the table is more than adequately sized to accommodate all your future ‘needs’.
