magic mouse vs other mouse for graphic design
Solution 1:
I can only comment for the Magic Trackpad: when I use it all day, every day, my wrist feel pain. It's far from an ideal solution.
I briefly used the Magic Mouse, but for my big hands it was too small.
I used (long enough) a Logitech Bluetooth V470, but every time I went to move the mouse after some seconds of inactivity, the mouse needed some tenths of a second to react. It was driving me crazy (as a side note: I knew of the issue when I ordered the mouse, but I thought: Meh, pussies, it will not be so bad.)
Therefore I would suggests the Razer Orochi (Bluetooth, as you requested). The mouse is incredibly accurate and has the possibility to be used wired as well.
Solution 2:
I find the wireless trackpad (Magic Trackpad) to be a much better alternative. Its more responsive and truly supports the multi-touch gestures.
Solution 3:
I'm a big fan of the Logitech mice for all things Mac. I feel like the extra buttons and the ergonomics are a lot better for making day-to-day stuff more efficient.
With my work computer, I've got the Logitech MX 1100 Cordless Laser Mouse and love it. I've got a similar one on my home machine.
The Logitech control panel allows you to map all the extra buttons to keystroke combinations, so it's very customizable to your workflow(s).
