Favourite PDA Programs

[chassis 33]

My XDA2 decided to go belly up earlier today and do a hard reset which, annoyingly, means I need to re-install all my bits on bobs on there, TomTom, POIWarner etc etc.#

What I'm wondering is, what 'aftermarket' programs can you not live without on your PDA?

I usually have all the Sat Nav stuff, Pocket Weather and thats about it, lthough I have had things ike Worms on there in the past.
