- I run win10 on a Vaio Canvas Z, a pretty recent machine. Graphics driver crashes regularly, although it remains stable doing so, screen freezes for around 2 seconds.

- when I wanted to install international keyboard profiles it has become way worse then older windows versions, which already weren't great. On OSX this is a totally solved problem. On Windows it would often show me the wrong thing installed until reboot, couldn't switch over to something newly added, the whole list is buggy.

- the terminal... god I hate it. It's stuck in the mid 90ies. Even Apple who supposedly doesn't care about power users anymore, has continuously improved its terminal application and it has become pretty great. On Windows I can't even have a decent color setting that would make all the standard unix colors readable without doing all kinds of hacks in .bashrc. Yes it's MinGW, but it uses the MS given terminal as-is.

- preinstalled PDF support is still a joke. Can't even annotate or rotate or really do anything with it.

- I can't get the preinstalled Mail/Calendar to reliably connect to gmail, gave up after an hour of fiddling around. That thing is a complete joke. And I hate Outlook's UI even though I've developed for it in the past.
