Well......
I´ve had a psion3 and 5
a palm V
and I now use a HP Jornada.
so............
a)Psion great for programing, good spread sheet and word processing, has a useable keyboard, screen as crap and too heavy for a shirt pocket but ok in nav bag.
b)palm light, trendy, good software but limited functionality(don´t care if I spelled it wrong it´s a crap word),screen crap, lots of add-on´s but low mem. basic OS very good.
c)Jornada, I´m in love. A real PC in your pocket. A little heavy but the screen is great. windows CE3(hate microsoft but the whole software package cannot be matched.)outlook,word,x-cel,ie(use it with my nokia via IR and can surf,v-slow 9600baud, but good for checking e-mail),plays MP3´s (long live napster) even watch videos!!!!!
character recognition software is beter than grafiti(palm) and you can run the screen in panarama so you can write long sentences. I even have a flight sim for it.(never use it honest.)sync via usb or IR very fast.
DOWN SIDE $$$$$$$$or £££££££££.
I have a sony net walkman too and thats even sexier....
