Brando Rii Mini Bluetooth Keyboard with Touchpad Review
 

The Rii Mini Bluetooth Keyboard with touch pad from Brando is a multifunctional device that helps a lot during presentations, and also incorporates an easy to use laser pointer. The product can be easily recharged with the help of the included USB cable. You can use it with your iPhone, or as remote control for a HTPC

I need to get one of these for my HTPC.

Good choice! The build quality does not feel cheap at all.

That's really neat. Is there anything like this that'll work with just a regular computer? I usually watch stuff through my laptop plugged into my TV and would love a nice wireless way to control it better.

this works with any PC that has a spare USB port :) (to plug in the bluetooth adapter, or use the build in adapter of your lappy)
