Prepare for Windows 7 with the Dell Multi-Touch Monitor ($470). This 21.5-inch Full HD panel is fully compatible with the multi-touch features of Win 7, and also features a two megapixel integrated webcam, USB, HDMI, audio, VGA, and DVI inputs, audio output, and a stylish integrated stand. Just remember to lower your arms every once in a while, lest you get sore arms from simply browsing your adult media collection.
Get yourself a little extra room without the hassle of adding a second monitor with the Mino Mini USB Monitor ($130-$230). Available in four models, each Mino Mini features a 7-inch screen, a single USB 2.0 connection with your computer, 800x480 resolution, and the ability to rotate to portrait or landscape view. It's not going to take the place of a full-size secondary screen, but it's more than enough to help boost your productivity.
