OS differences?

[NorseMan]

just a little confused. I noticed my 2215 has an OS called "Windows Pocket PC 2003 Premium" and the new releases (rx series) have something called "Windows Mobile 2003 2nd addition/pro edition).

Any major differences between the two? Thanks.

The professional edition is designed to fit smaller ROM such as the 1930/40. Some applications such as Reader and Media player and Messenger is not preinstalled in ROM but on the cd that comes with the ipaq, and you can choose to install them in RAM.
