Query: It works, but very slowly

I bought and used the pen for a while just to see if I liked the system. It does work as advertised, but it is too slow to really be of any use. A better choice would be to save the money and spend it on omnipage. I priced things after using the pen and realized that I could buy a better scanner 9x12" with omnipage for under $90. Even the lite version that came with the scanner is better then the pen. I was able to resell the pen to someone else since I had no use for it.
