The Price: $130 for UM-710, $170 for UM-730, $200 for UM-750.

The Verdict: Decent, but not phenomenal. Regular readers should know how much I love adding monitors onto my setup, so having a 7-inch, 800x480 display for widgets or chat windows or small, always-open apps is a great idea. Well, it is, but the implementation is slightly lacking.

The Mac support, after a good amount of back-and-forth with DisplayLink, works just fine. It's plug-and-play and can be detected automatically (and rearranged) using the built-in OS X system control panel. Even the webcam is usable, which is semi-notable because of OS X's finickiness at accepting webcams. The Windows support has no notable problems either, even under Vista, provided you install the correct drivers in the correct order.

What's lacking about all versions—no matter what webcams or touchscreen features are added on—is that 800x480 is really hard to read on a 7-inch screen. It's usable, but you don't want to stare at it all day. The 7 inches are suitable for your calendar, or your email alert window, or your Twitter client; something you want to keep visible but don't check all that often.

Touchscreen feature works alright, but is finicky under Windows, and the webcam isn't quite as good as the built-in iSight on our MacBook Pro. But it is a webcam, and you can have conversations with it.

So as long as you're using this as a second, third or fourth monitor, or are tight on desk space, or don't have a spare DVI/VGA output, it's not a bad solution. We love having extra display space for things you want to have access too quickly. However, For $130~$200, you could get a regular-sized monitor and use that instead, meaning only people who fall into the above categories should consider this product. [The Gadgeteers]
