I said I would post the results from running the Upgrade Advisor, though they are all a bit of a jumble in text form but are far more readable in the HTML that the report was originally generated. The gist of it seems to be that the machine spec is fine but there are a few surprising, at least to me, items it has thrown up;
It seems unhappy with my less than 18 month old Canon Printer and my less than 6 month old MS Mouse as it seems that Windows 7 will not support the version of Intellipoint currently installed.
Photoshop Elements 4 won't be happy, but it wasn't happy with Vista either but still ran, I would need to uninstall iTunes and NovaBACKUP 10.3 before installing Windows 7, though I think Nova have already released a Windows 7 compatible version but I haven't checked to see if it's a free upgrade. Windows Mobile Device Centre which I use to connect my Dell Axim PDA would also have to go but, like the others, can be reinstalled after the upgrade.
The advisor indicates that Outlook 2007 is OK but the Man from Aunty had problems and maybe ought to be added to the list of possible hiccups.
I don't suppose any of these represents a strong enough reason to dismiss the thought of upgrading but it does look like it might add another couple of hours to what the BBC report suggests is already a lengthy process.
