I'm looking for a replacement for my MagicMouse. I've kind of had a love-hate relationship with both units I have had over the past 4 years. I love the features and gestures and the fact that it is Bluetooth. I hate that the slightest tap or knock causes it to loose connection and that the tracking and clicks don't seem as responsive as other mice. For example, I have a cheap logitech M310 wireless plugged in right now and the difference in tracking and click responsiveness is very noticeable. What are the favorite alternatives out there for the Magic Mouse? I'd prefer bluetooth and I am left handed, which I know cuts out a large portion of the field. Is the new rechargeable version of the Magic Mouse any better than the old ones?
