Thanks to everyone who gave me suggestions and advice on moving towards better time management through technology. (My dyslexia gives me a rather fluid and vague grasp of the flow of time - which tends to get me into interesting situations occasionally). I have listened to what you've told me. I've also gone shopping and looked at different models of netbook and smartphone. And prices, of course.
Ivory kindly let me play around with her iPhone on Thursday - which has given me more of an idea about how I might use one.
Yesterday I came to a decision. I'm going to shift a load of my organizational stuff onto Google calendar, google mail etc. But I am going to hold back from buying any gadgets for a few months. (I am having a fairly intensive period of writing during the next 6 months, so my organizational load will be limited). Then, when the next google phone comes out, I will probably go for that. Presumably it will be called the G2. By that time, I'll probably be renewing my laptop as well - and will go for one of the long battery life Samsung netbooks.
Why the Google phone rather than the iPhone? Simply because of their open-source policy. Whilst I have complained about Google's attitude in trampling over copyright holder's rights, I am perfectly happy for them to release their own intellectual property to the creative commons.
Apple's more-or-less opposite approach of centralisation and secrecy seems less wholesome and, however beautiful the iPhone is, I feel uncomfortable with it.
So there we go - thanks again for the input.
