Tried a bunch of Linux distributions: Caldera, Slackware, Redhat, Mandrake, SuSE, Debian, ....
Then came Corel and I thought it was the greatest thing since sliced bread. Clean, smooth, effortless install; everything working right out of the box; all the necessary applications; professional look and feel.
Microsoft must have had its eyes on the situation as they immediately bought into Corel. The next thing you knew, Corel was history.
Ubuntu is not nearly as pleasant an experience as Corel was back then, but it just does a lot of the basic stuff right, even though it does leave a lot to be desired in terms of polish, privacy concerns, look-and-feel, usability, openness, etc.
Hopefully, Canonical attends to these issues or someone else takes the helm in improving things.
