This is obviously not an easy one, but:
If the Windows XP user have some way of keeping there windows installation completely intact and running it alongside Ubuntu this would reduce the barrier of having to completely ditch Windows and move to Linux.
I know about dual booting, of course, but _I_ don't wan't to have to shut down all my applications and reboot just to see how that thing in Excel works so I can replicate it in OO on Linux (or summat).
If the user had the option of keeping their previous Windows XP installation running in Virtual Box or something, and possibly having all the Win XP hardware support (e.g. USB) to smooth the transition.
Now that would be something, wouldn't it?
I have a VBox VM with Windows for developer support, so I know it is possible, I also know it is a bit Herculean, but the question is: "Would it make people migrate who otherwise wouldn't?", E.g. small businesses.
I am also aware of problems moving WinXP to a VM from native, but these have been fixed.
