I have been on the hunt for an app that will provide an easy method of getting travel itineraries onto my Treo 650. I am only concerned with flights, hotel and car reservations, and don't need all the other bells and whistles offered by pricey apps such as Worldmate.

I prefer an app that has a desktop component with a HotSync conduit, as it makes data entry a bit easier. Besides Worldmate, I found an application called TravelTracker, which is not bad and quite affordable, but it could use a little update on usability and look & feel.

Does anyone know of any other travel itinerary apps that have a desktop companion?
