Using mine as I type this comment. Love it.
Lenovo must have a TON of these to sell.. they appear frequently at this price. They have one possible major issue: They operate in the unlicensed 2.4 Ghz spectrum with an unknown protocol. 2.4 Ghz is shared by Wifi and bluetooth devices. The problem is that both bluetooth and wifi have published mechanisms to deal with interference (DSSS and FHSS if you want to get technical). Wifi slows your rate down and bluetooth hops somewhere else. I have no idea what this keyboard does, so if it doesn't have DSSS or FHSS, then it will impact your current wifi or bluetooth spectrum (not KILL - degrade). I have this keyboard and it works, but I did not analyze its emissions or my WIFI bandwidth before/after. If you are in a crowded spectrum area, then I'd look for another device with bluetooth.
@jaf323: They are probably trying to push out the leftovers, This is the newer model: http://shop.lenovo.com/SEUILibrary/controller/e/web/LenovoPortal/en_US/catalog.workflow:item.detail?GroupID=38&Code=57Y6678¤t-category-id=E9ADAEB6787146E29B78400A33E7FE8A&&hide_menu_area=yes
I have a 2.4 ghz Spectrum analyzer, I could try to test to see if it is directly interfering on a certain Wifi channel.
