After I uploaded my music programs (Cakewalk, Addictive Drums, etc) and getting them licensed, I came to realize the "@" which is also the "2" button does not work. I have to copy and paste from the Character Map. Not a huge deal as I'm not using it for email (I compose music during lunch), but still, check your computer thoroughly when you receive it. Battery is good for about two hours. Other than that it has worked ok. Not bad for what I paid for it.
