[Q]: if you plan on upgrading an older computer to Windows 8, this is a &#34;must have&#34;. And it's a far less expensive option than getting a touch screen monitor.<br /><br />now don't get me wrong, there's a learning curve associated with this but you might as well get over it now, as I feel the venerable mouse has seen its last days.<br /><br />the 650 performs well, supports all those new Windows 8 gestures, has a long battery life, and has a quality finish.
[A]: Positive Review

[Q]: After carefully following the instructions several times and getting unsatisfactory results, I contacted technical support. Their answer: \"Compared to default yes it appears warmer, but that is expected.\" What a waste of money.
[A]: Negative Review

[Q]: I got this hub so I could plug things into the back for more-or-less permanent connections, and also have plugs on the front for temporary connections (camera, iPod, etc.). The hub can be mounted on the &#34;foot&#34; either vertically (as shown in the photo) or horizontally. There's no non-skid on the bottom and the unit is very light, so it tends to move around on the desk.
