Pretty Data Accruer

At the risk of having you all do what Cam did and stare at me seriously and then ask "Alright, what have you done with the real Sophie?", I'm thinking of buying a pda, probably this one. But since I've never owned one before, and Cam just had a dodgy Palm ages ago, do any of you past-or-present pda purchasers have any advice?

It's mainly to hold text files with all the procedures for work (since there's a lot, many of which aren't written down anywhere and change constantly), lists of things to buy and do, contact details, bus and train timetables, and writing down my Brilliant Ideas as I have them. I'd have gone for this one but you can't organise your files into folders, and labelling them into categories just isn't the same. Also, no downloading things off the internet, where's the fun in that?

And now, work.
