Strange I may be, but I love the touchscreen option. Can't imagine not having it now....
I am, naturally, totally dependant on my Treo - it has my timetables, databases, eBooks, dictionaries, music, documents - in fact, it does everything but make my coffee for me...!
Even though I am pretty clumsy, I rarely hit the wrong icon or get frustrated with it. It might just be my choice of handset, however, as other touchscreen models I have tested I have really disliked...
The keyboard is, of course, very small, but I find it fine to use - no good if you have long nails or big fingers (I don't).
I use a Treo 650 (Palm OS) with assorted programs from various sources.
