Earlier today users were briefly able to download a tool to assist the migration from Mac to Surface. It was later pulled, presumably because Microsoft wasn't ready for it to go public.
It's very existence speaks volumes for the progress Windows has made against Mac OS. For whilst the tool is branded for Surface owners there's no reason why Windows owners of any hardware persuasion shouldn't benefit from it.
The idea that users would be migrating from Mac to Windows in sufficient numbers to make a tool worth developing would have been laughable even three years ago.
Now it seems a perfectly logical thing to do, as Microsoft's Surface has helped drive the PC market in new directions.
Whilst Apple has lagged, with lacklustre upgrades to its desktop and laptop ranges, customers have been finding more and more reasons to switch to a PC.
Having bucked the trend on PC growth for a while, Apple now find itself stuck with no real entry in the growing hybrid market.
Microsoft, on the other hand, has built a substantial hardware business and forged a path for its partners to follow.
