While a new generation of Windows Mobile devices heads for release, the current generation is mired in the calendar swamp.
That is, if you don't want to sync to other calendars via Outlook, which I don't.
Oh, and if your Windows Mobile device is just a PDA, better trade it for a Windows SmartPhone, an iPhone or something else. Otherwise, you're going to have one disappointment after another. Plaxo Mobile Plus is just the latest. (what do you mean, you don't have a carrier associated with your Windows Mobile device?)
No new negative SwampDrain points here for Plaxo. It's just a well-worn path of disappointment.
Meanwhile, River is ready for her iPhone! Like so many others.
