Interesting. Looks like this one is out of stock.
BTW this is about 1/2 the price of some of the other cheaper options on newegg.
I have the BTC. I like the design and look, but 2 things NOT good
1- the performance is terrible, barely get 8 feet away and start to lose connection.
2- NO scroll wheel, this is a dealbreaker if you surf the net with it (especially these sometime long forum threads

)
I don't think it is still on the market, but I also have a nMedia "MCEKB". it is designed similar to the MS MCE keyboard, but RF with an optical trackball.
IMO, the BEST HTPC keyboard I have had was the "good ole" Liteon "Airboard"
Just got a new router and I think the wireless interferes with the RF units (can not even USE my Gyration remote now), would like to get back into IR.
