So, as you all know,  I do lots of work using the .Net Compact Framework.

However,   I was reminded today about how mobile web pages still make lots of sense for lots of different line of business applications.

At Anglia (my day job), we have consultants, developers and a salesforce pretty much out of the office all the time.   We use our mobile portal delivering content from SharePoint, Dynamics NAV and CRM  with mapping data from Virtual Earth.

It works great letting any one of our staff do any of the following from their mobile device -

Timesheet
Expenses
Mileage Capture
CRM customer lookup - including maps to customer locations
Helpdesk
Leave, booking holiday
Raising purchase orders/requests
Company news

etc...

The application to achieve this was built end to end in about 2 weeks elapsed.
