I think that the linux desktop has improved dramatically every year, but there are issues as well. This really isn't unique to linux though, no OS out there fulfills every user's needs (and in the case of linux, there are so many different people/groups with different philosophies making distros, that it can be super hit or miss). I've had my fair share of normal updates breaking the system, or installing ubuntu and getting booted straight to the tty since it didn't ship with nvidia drivers at the time. Even now, when I run an update, I have to manually delete the updated nvidia driver and manually downgrade to the old one because I simply get a black screen with the new one.
The issues are always managable, fixable, but I think that they do make linux very difficult for people without the time or understanding to troubleshoot the problem.
But, when I was on windows I had plenty of things break there too, ads in the start menu, that sluggishness that windows always seems to get if you don't do a fresh install every year or two. I had a game that would crash on boot if I had my USB headset plugged in. And of course, updates breaking the system randomly.
The issues you seem to be having aren't normal, and while I'm tempted to blame Ubuntu, I'm not sure. Ubuntu makes some really strange choices, I feel, and did cause me more issues than other distro's I've tried.
But really the core of what I'm saying is that depending on your use case, linux might suck, but it can also be far better than other OS's.
