I am now using NoviiRemote, works like a charm
I am using Emu48, this is an emulator that allows you to use the HP49G Graphic Calculator
As for Agendus Pro (program that combines Calendar, Task, Contacts...), I haven't found the PocketPC version
www.iambic.com
The Pocket PC version is called Pocket Informant, they also have FlexMail, I'm gonna try them both
I really liked their Palm versions
