Hey Seonaid,
I too wanted a PDA very badly. They were new and cool and I wanted one. But I wasn't sure I would use it enough to justify the cost so I held off and held off for years. I didn't want to buy a cheap one, like the system and regret not getting a nicer one, nor did I want to get an expensive one and have it become an expensive toy that got stuck in a drawer.
Finally my wife found a old Palm Vx on clearance at a store for $100 (this was several years ago now when they went for $300).
Elated I got it opened it, turned it on and.......
It said Hola! That's right it was a Spanish langauge Palm. Well several calls to Customer Srervice later, I had an English Language Palm.
I learned Graffiti and used it for a good solid year. I should say I was using a Franklin paper system before this. But what I found with the Palm was that it was a pain for me to wait to turn it on, enter the info etc. Plus, even though I had a super cool case, I like to keep business cards and scraps of paper with notes in m organizer. So my Palm had all these post-it notes on it!
Then one day it stopped. Oh it still worked, but it always thought it was March 12th. I would reset it and it would revert to March 12th. So I put aside.
I am now using an inexpensive, small paper calender from Franklin and it workd for me. I have a set schedule (Academia as you know) so I don't have to schedule a huge number of things. It's easier for me to write the two or three things I need. I don't refer to it often, but don't need to either.
Now I do miss extensive contacts and backing up the data and used the Palm Desktop for years after I stopped using the Palm.
So truly think about how much you will use it, what you will use it for. As others have said there are those that love them and can't live without them. I don't have many scheduling needs, so the usefulness is more limited for me. Nor do I have business contacts. I just wasn't using it enough to warrent the expense or time.
Figure out what you want, what you need and go from there. Even if it's just for Bejeweled
Oh I will say I used to have (and still have) an old Sharp Wizard. I LOVED that thing. 128kb, fold open keyboard, not a tablet style. That thing was easy to use and did enough that I could use it easily and quickly. If it could sync, I would still be using it. Got burned once though and it crashed and I lost all my data and contacts.
