I should also add an explanatory note - I have a 32GB iPod Touch (ie an iPhone without the phone

) which I think is absolutely great at what it does (I use it primarily as a portable video player), but I find personally that Windows Smartphone makes a much better general-purpose PDA; its synchronisation with Outlook is excellent, and far better than what the iPod Touch/iPhone have. I agree that "Safari" on the iPod is a better web browser than Mobile IE, but for general "data retrieval" type apps (including reading eBooks), I prefer Windows Mobile. I don't like using my fingers for all "UI" stuff - there are apps (including book readers) for which I find myself that hardware buttons work better.
