On the other hand, I've encountered issues on OSX that I simply couldn't fix. With Linux, if you care enough about a bug you can generally find some workaround. (Assuming it's not driver related!)
Fair - but too often the bugs are driver-related. I realize that this is kind of unavoidable for open-source software in our economic system, but it doesn't make it any less annoying.
It was the driver bugs that drove me back to Windows - doing multi-monitor is a pain in the rear, and suspend/hibernate would often break on distro update in the rare cases they worked before. Getting an up-to-date Web browser is a big plus for Windows over most Linux distros too (I know about Debian testing, Arch, PPA's, etc. - I said "most").
They stay well up to date, but not because of Ubuntu. At least the last time I used Chrome, it required a PPA from Google, which is updated by Google. The Firefox repo is updated by Canonical's apt staff.
