Standivarius Aero laptop stand
The stand itself is very thin, and largely unnoticeable when attached, but you'll have to make sure it fits your laptop's footprint (there are two sizes available) and that you don't mind having it hitch a semi-permanent ride on the laptop's bottom panel.
LapDawg Pug laptop stand
The design reminded us of a vintage TV tray, and you can use the Pug flat on your lap, with the legs half folded out (about 13 inches high), or with the legs fully extended (about 19 inches high).
Cyber Clean keyboard cleaner
Cyber Clean is one of those ubiquitous products one sees sitting on store shelves without ever giving it much thought. It's essentially a ball of fluorescent green goo that you mash into a keyboard or any similar device (obviously make sure it's turned off first), and the tacky surface picks up dirt and grime. It costs a few bucks for a small pouch, or up to $49 for a giant tub.
You're supposed to be able to literally fold the dirt and debris back into the mass and use the glob over and over again until it loses its bright green color--but that sounds a little icky. We think of it as a single-use item.
HP Wireless TV Connect
We're more partial to the new breed of wireless HDMI transmitters, including the HP Wireless TV Connect and the similar Asus WiCast. Both have two small router-size boxes (and both run $199). One connects to your laptop's HDMI output, the other to the TV's HDMI input. Add power (USB for the transmitter, A/C for the receiver), and you're good to go.
While it's a little clunky looking, the system turns your TV into a wireless second monitor, and streams Blu-ray, games, or anything else that can play on your laptop.
Astro Mixamp 5.8
Want to connect to a stereo in the next room? Take the headphone out from your laptop (or an optical out if your laptop has that) and connect it to the palm-size transmitter. Then plug the smaller receiver into your speakers, again via a one-eighth-inch audio cable. There's even a large volume wheel on the receiver, and the system supports 7.1 audio and gaming headsets.
