Thanks for the information - I had wondered why I hadn't heard about an operating system upgrade - got my E335 from Office Depot with their great rebate deal in May (Another ANARDTECH deal discovery) so I can't complain as much as those that paid full retail. My previous Compaq IPAQ - I paid $24.95 for their previous operating system upgrade - I didn't realize that the 2003 software upgrade was supposed to increase performance - don't do WIFI or internet with mine so most of the other features are not useful to me.
