I respectfully disagree. In my experience, Linux isn’t any buggier than Windows, and hasn’t been for a decent number of years.
The main thing hurting Linux adoption in my opinion is that the best-known beginner distros (Ubuntu and Mint) just aren’t very good compared to most others.
OpenSUSE is the best beginner distro in my opinion, with Fedora as a close second, and LMDE would be the best if it was feature complete.
