They have improved a lot, but there are still the forced restarts, as well as the poor document recovery of the office suite. Together this is a bad combo as I'm constantly worried I might have lost some data in the documents I work on.

They have improved the document recovery quite a lot in the last two years, but they still manage to make the process rather confusing, so sometimes I accidentally save the version with the lost data instead of the other.

OpenOffice had this figured out some 15 years ago. I never lost data to OpenOffice, and I was running it on a laptop (essentially) without a battery.
