The Microsoft Natural Elite model 59758 was the best keyboard ever made and it saddens me that it hasn't been reproduced with modern connectivity. Microsoft would do itself a great service by reproducing these keyboards with newer USB/RF technology build in. The curve, the key response, the positioning... all great. And it was their very first run of a natural keyboard.
This keyboard is identified by it's cursor key positioning. Rather than the "+" design of the keys, they are in an upside down "T" position.
Finding one new, in box, runs you approximately $150 USD so it's a pricey venture to nab on of these in their virgin form.
Any companies out there willing to make reproduction models of this fantastic keyboard? I'll gladly pick them up.
