Very nice capability for gestures, like a trackpad; limited Bluetooth range; computer the drops Bluetooth connection
on June 20, 2015
Apple's 2015 update to OSX 10.10 ("Yosemite") takes some features from iOS 8 for iPads etc. and transports them to the computer, including gestures like swiping that you can use on a touchpad -- or on the Magic Mouse, to some extent. The ability to use gestures is moderately useful, and the physical design of the mouse is fine. It has only one large "button" that takes up the whole surface, but you can set it up so that you can right-click on one side and left-click on the other, which as a refugee from Windows is nice. You can also scroll with your finger despite the absence of a scroll wheel, and scroll left & right. The scrolling feature is worth paying the price of the two possibly related flaws in the Bluetooth connection.
Flaw (1): It has very limited Bluetooth range. It's OK next to the computer, but if you get more than about 6 feet away, the new Mac Mini I have doesn't respond. It's like a dropped cell phone call. Bluetooth is supposed to work up to 10 meters (33 feet) away, but this Bluetooth on the Magic Mouse loses signal at only 20% of that range. And (2) after using two of these on three different current-model Mac Minis, my experience is mediocre in terms of having a stable Bluetooth connection. The mouse loses its link fairly often - at least once every day or so. The fastest way to restore the connection seems to by putting the computer to sleep and then waking it up. Apple's support site says that other 2.4GHz devices like cordless phones can cause interference with the Bluetooth signal, but I have other Bluetooth devices in the same environment that do not drop their connections. Too bad, because when the Magic Mouse works it's very comfortable and has useful features - notably the very smooth up-and-down scrolling and the ability to scroll left and right.
