I am always looking at different keyboards and recently I found this Ultra Mini Keyboard. I know you are thinking, is this a Logitech? It certainly looks like a Logitech. From the box down to the fonts it looks like a Logitech, but actually it isn’t. This is actually a knock off that has been packaged to look exactly like the Logitech packaging. That said, it is actually a pretty cool device for $16. It is about the size of a phone, includes a touch pad, and a USB receiver for your computer. You are not going to want to type a novel on it but for basic navigation and searching it will do a decent job on your HTPC.
Not much that I can say about a $16 dollar keyboard except that for your basic navigation needs it works pretty well. It has the advantage of being very small so can leave hanging around on the couch or a coffee table. It even has an on/off power switch so you can conserve battery power when you are not using it. Keeping the use case into perspective, this fills a void at an extremely low cost, and so far I am happy with it for the occasional use. For me, I mainly use it for periodic updates, configuration changes, and some light search once in awhile. I think if I had to use it daily I might feel differently, but for occasional use it does the job.
