The backup requirement shows a lot of self-awareness from Microsoft, but it's still too hard to migrate a Windows machine. Contrast with a new Mac, I wait a few hours, and all my stuff is identically copied over via the built-in tools, and it feels like the same machine. With Windows, preferences all over just don't really copy. I don't care about a few .docx files, I want hundreds of legacy apps and settings to be preserved. As it is, it's more than a week of work when you get a new PC.
