I'm going over fully to the IT so for me too the VM is a stop gap. I find gpe calendar, todo and contacts fine for what I need.
I now use Google Calendar on my PC, gpe on the IT and sync them, a seamless procedure.
The big problem with contacts for me is the lack of import facilities. A csv option is needed at least.
Password storage looks to be a long term problem at the moment.

I've bought the Wayfinder mapping to replace Tom Tom on my Palm but I still use the Palm BT GPS module in the car as my Peugeot has the heat reducing windscreen option which inmpeded GPS signals. The maaemo mapping is OK but Wayfinder is a good replacement for Tom Tom.

I find the lock on time of the IT GPS module slow but so is my little Garmin hand held. Nice to have it there for when I'm out walking or cycling, though.
