So I went out and bought the wireless Mighty Mouse. My first impressions are not good. Although I like the functionality, it just doesn't feel right - it feels a little flimsy and I can't get used to the scroll wheel. To top it all off, mine has a defect (it won't scroll left....only up/down/right). So I'm going to take it back to the Apple Store tomorrow. I think I'll end up getting something different, but I would like to keep with a Bluetooth one so I don't have to plug anything into my computer. Recommendations?
