The Logitech MX1000 is going for $69 which I find expensive. The price will sure drop considerably over time.
First laser mouse
Awesome precision
Cordless
Li-Ion battery
Lots of buttons
Expensive
Software problems
Bumpy plastic remains from production at thumb rest
If you have the money and want to have the latest and greatest, the Logitech MX1000 is the mouse of your choice. If you already own a solid optical mouse the added benefits are not worth the purchase in my opinion.
