[Therion] PDA

[Markus Boldt]

Hi all, 
slowly the time goes to end, there we can buy cheap "old" PDA with
Winmobile. Pockettopo works only on Win platform and small cheap devices
with Windows as OS are seldom. And our devices in use are growing older.
What do you all use? What alternatives are possible. I know about some so
called APPS for Android, but do they work? 
I hope you have the same opinion - that this is the right platform. 
Greetings 
Markus
