Installed and working wonderfully. It's a GREAT mouse. I hope I don't develop problems with it, but I've been REALLY impressed.

Everything has been working as advertised for me. I just wish there were two more buttons so that I could invoke Exposé and Dashboard.

I have a early 2009 macmini and the Magic Mouse works wonderfully. No response issues at all for me. I don't have any third party mouse software installed as it used to be useless for me when I was using windows.

This is the best mouse, so far, I have used despite its lack of middle button for now. I don't go for hand hugging so-called ergonomic mouses because I change my hand position regularly using the mouse to avoid fatigue and cramping, hence I like the sleek low-profile. When you are on the keyboard and want to scroll down a little just glide your finger over the top of the mouse to scroll, no need need to grab hold of the whole mouse. It seems like the mouse was made for me.

I think they should of taken it one step further, and put in some pressure sensing devices and a tiny bit of flex in the shell just enough so it can register right click without having to lift your finger off (I don't mind doing this). I wonder if that is technically possible.

People with more than just plug & play going on may have issues with the mouse being seen as a top mounted trackball.

Works great for me, and I think the only problem would be with existing third-party drivers. Logitech Control Center and Microsoft's drivers are known to be problematic enough, so un-install them before the first time you hook up your Magic Mouse.

USB Overdrive has usually played nice with other drivers, but I would also un-install that until they claim official support for the Magic Mouse. They came up with Mighty Mouse support pretty quick, so I imagine they will do the same with the Magic Mouse.

And I've had to help more than one person so far with the "install/setup" process. For the record, it is connect to the Magic Mouse like any other Bluetooth mouse, then run Software Update, and restart when prompted. After restarting, go to System Preferences->Mouse and configure to heart's content.

Haven't had a problem with my two personal installations and a handful of ones that I've helped with,

I've just had mine for a week, but so far it's worked great. I wish the ergonomics were better, but that's just being picky.

... a real, hand-fitting, ergonomic mouse. If there is a place where MS leads over Apple, it's in their selection of mice.

Come on, Apple - you can make TWO mice: the Magic Mouse for those who prefer the technological wonder in the pancake package, and a nice hand-fitting, ergonomic mouse.

I've lost my swipe to navigate function on the magic mouse and on my track pad. I haven't tried to trouble shoot it yet (hasn't bugged me much), but I'll try uninstalling my MS mouse drivers.

Even so I really like the magic mouse. I'm hoping that future updates may allow swipe functions to envoke other functions.

Is there no middle button ? Damn ... I really loved it to bring up the application switcher. Maybe with a software update ? ...

I was having trouble at first. Updating the mouse software, removing USB Overdrive, making sure the Magic Mouse was recognized (re-searching), and restarting the OS fixed everything for me.
