As for the older Sculpt Comfort Mouse, Microsoft now sells the keyboard ($59.95) and mouse ($39.95) as a new bundle, known as the Sculpt Comfort Desktop ($79.95).
Unfortunately, it's difficult to move past the fact that both of the the two major mouse manufacturers--Logitech and Microsoft--sell ergonomic mice geared at right-handers. Granted, there are "neutral" mice that can be used by either hand; the Logitech LX8 was my favorite, until I lost the wireless dongle.
Microsoft's keyboards and mice have been rightfully praised for their ergonomic design, and the new Sculpt Ergonomic Keyboard appers that it will continue that tradition. But how ergonomic can a right-handed mouse be, for a lefty? As a lefty myself, I've dealt with scissors, desks, golf clubs, and gear shifts all designed for right handers. At least Microsoft has freed the number pad from the tyranny of righties. But releasing an ergonomic mouse for right-handers on Left-Handers' Day? It all feels a bit rude.
