To me, the OG appeared to run slower that the 200. In addition, the screen was not as large and not as many characters will fit on the screen (and what was there was not as legible). Being able to use a pen on the screen is great, however. This appears to me to be just what HP is advertising it as - an organizer for the non-techi types. I'll stick with my 200 and hope that the next generation of the 200 includes pen capability.
