I really have no complaints about the Magic Mouse. It's a superb choice for a mouse and fits in perfectly with my Mac scheme on my desk. The design just so happens to fit the shape of my hand almost perfectly, however I find myself gripping the mouse on its sides and picking it up when I want to scroll sometimes.
Also, the one minor design flaw I mentioned in the title is the battery cover. The mouse has fantastic battery life (I've had it for almost 2 months now and its only down to 56% on the first pair of batteries), however the battery cover is very sensitive to and force applied to it. What I mean by this is when you lift up the mouse about an inch or so and drop it or set it down a little rough, the battery cover can pop right off and it never seems to securely fasten onto the mouse itself. The cover also seems a bit thin to hold its own.
Besides that minor problem (it occurs rarely), this is a great mouse and I'll never use any other mouse for my Mac.
