Do you have any data on that? Because I've seen a few (sample size ~4... so mine isn't useful data either) non-technical people doing this and in pretty much all of the cases what they wanted was to keep using the same software they'd been using for the past X years. Getting their "computer guy" (usually me, or some local teenager) to copy files over for them was their preferred way to move onto a new computer.
No hard data, but it's what I've seen the people I know doing. Lately they buy Macs, but when they buy Windows machines, they usually choose the pre-installed Office because it's easier than installing it later.
