Some touchpad RF keyboards to try-
I bought all the above except the Logitech K400, plus I bought the IOGear GKM681http://www.iogear.com/product/GKM681R/
Since "touch" is currently "in" due to phone/tablet interfaces, we may as well get used to it, especially those of us partial to trackballs or pointer sticks.
On the bright side, most laptops/netbooks have been using touchpads for years, so I'm getting more used to touchpads myself.
The new "thing" is mutli-touch capability on keyboard/notebook touchpads, recognizing multiple fingers and gestures for specific functions- a nice development on the commodity touchpads.
The GKM681 was on sale at Microcenter for $29.95 two weeks ago- may still be that price, at least walk-in at the store.
Reviews for the GKM681 on amazon complain about range, but it appears acceptable to me in brief testing. I'm impressed with it for the money. Would be perfect it the keys were backlit, but other than that, the design/layout is "perfect" for a mini trackball HTPC RF board- all keys, including F-keys, hardware scroll wheel, well placed mouse buttons, good build quality.
The coolest board of the bunch ishttp://www.geeks.com/details.asp?Inv...SK-PB&cpc=RESX
I got it Cyber-week for ~$28 free shipping, so I bought on impulse to try it out. The size, integrated rechargable LiOn battery, touchpad, and backlit keys had me intrigued.
It works perfectly in Xubuntu 11.10 out of the box. The backlit keys are excellent and easy to read in a dark theater. The keys are small, but you use this board like a cellphone board, "thumbing" the keys with both thumbs to type, like texting on a smartphone with physical keyboard (slider phones, etc). No, you won't type long prose with it (though you *could*), but that's not what it's for. The touchpad works well, just a tad small surface area wise, though that's the point of this board. The receiver fits into the keyboard and you can carry it in your shirt pocket like a small calculator. Bonus- it has a LED flashlight built in, running off the same liOn battery! Coolest board for HTPC I've tried to date. Includes access to all F-keys F1-F12 via the Fn modifier, so you should be able to go into your BIOS at bootup with this one, though I haven't tried it yet.
I've only played with it for less than an hour, so there could be some downsides, but for $30 shipped, the IPKW250FUSK is the dream ultra-mini HTPC board.
I'm also impressed with the GearHead-http://www.pcgearhead.com/wireless-d...php?PrdID=1003
though it doesn't have backlit keys. Range appears very good.
