My Kensington Ci70 wireless keyboard stopped working after a couple of years of daily use.  I really enjoyed the way the keys felt when I typed but didn’t like that it was wireless.  Therefore, I decided to purchase the Ci73 keyboard, which is now only $25, half the price I paid for the Ci70.  The Ci73 feels better than the Ci70, and tons better than a traditional keyboard.  My wife even tried it out and didn’t want to stop typing. 

I was using a dell keyboard last week and felt some tightness in my wrists, something I never experienced with the Ci70.  The ease at which this keyboard types is incredible, I don’t want to stop typing on it.
