Found on HP's support site is a document revealing that the Microsoft Outlook setup will not be available on the Getting Started CD shipped with every HP iPaq manufactured after March 2007. Because it is a support document, the solution given there is that customers who need Outlook will have to purchase a copy separately from Microsoft.
Windows Mobile device manufacturers usually bundle a standalone copy of Outlook for those customers who may not use the Microsoft Office suite (of which Outlook is a component). This means extra cost for those without Outlook as it is necessary for syncing of contacts, emails and calendar information. When contacted, HP was not yet able to comment on the reasons for this exclusion, or whether it will result in a reduction of the iPaqs' prices. Also, it is unsure whether the move affects all iPaqs or just those shipped in the US. More information to follow as it becomes available.
