magic mouse is NOT ergonomically friendly
I'm accountant at a big business management and tax company and I do a lot of clicking and dragging files from one location to another.... and I have to say that the magic mouse is and it's rigid design hurt my index finger when using it more than 30 mins a day (and I'm working 10-12 hours typically). I love the sleek design but I think I'm going to have to sell it as the pain has gotten worse over time.
