Logitech MX Revolution

I bought the Logitech MX Revolution mouse a little over a month ago and figured it's time to make a short review.

Initial Impressions
A very well designed mouse that's great for productivity, yet has a few minor setbacks.  I've never been a fan of spending more than $20 on a mouse, but this was definitely a great buy.  I find the automated switching scroll (free scroll to click scroll) to be very intuitive.  The ergonomics also make this mouse quite comfortable.

Pros

• Very comfortable design
• Relatively portable,  despite being designed as a desktop mouse
• "MicroGear" scrolling mechanism
• Auto free scroll based on scroll speed
• Rechargeable

Cons

• The receiver is a bit large for notebooks, but still has a small enough footprint to carry around.  (should have included the, smaller, unifying receiver)
• With extensive use (and not turning the device off), the battery lasts about a week for me.
• Thumb wheel does not scroll.  This was one of the first things that annoyed me upon use, it's not a major setback but I don't find navigating through windows to be as intuitive without an actual scroll wheel.
• Laser is towards the right side of the mouse.  This personally does not bother me, but if you like to lift and reposition your mouse this can be cumbersome.
• You cannot center click when auto free scroll in enabled, this is obviously software related...but drives me absolutely nuts!
• No changeable battery...it's completely integrated, poor design in many aspects. (both business and consumers alike)
• Picky about some surfaces but still much better than most optical mice.

That's about it for a general review, but of course there are so many more things to consider.  Overall this is a great mouse, one of the best I can find in the current market; I just wish it would have been slightly more refined.
The Logitech Performance MX was released after I purchased this mouse, which seems to have addressed some issues I have had with this product.

Best described...the best mouse I found on the market at the time of purchase, but far from perfect.  Be sure to check out the Logitech Performance MX too, a newer model.
