Query: Great keyboard!

This is a great keyboard, especially considering the price. The layout of the keys is very good. Many slim format keyboards do not have a control key on the right hand side these days, but this one does. The commonly used keys (control, alt, arrow keys) are placed close to the resting position of your fingers. The keys have a good feel to them, solid but not too hard to push.
