I too am frustrated by what appears to be lack of extensive testing by the Ubuntu team - especially on LTS releases.
No OS is perfect, but at least in Linux I can find and fix the trouble I come across - instead of rebooting and hoping the problem goes away.
Perhaps the real issue is that it is easier to complain than to learn, in which case, by all means stay on Windows. There's not much to learn there.
When you start investigating the open source realm, you find that the world you thought was so big just shrunk to an amazingly small dot. It is daunting for one that lacks courage. I've been on Linux 10 years, and I still shake my head at the huge list of free software available for so many fields.
Yes, it does come with a price. You have to learn.
Whoever came up with the phrase "There is no such thing as a stupid question" obviously never had the internet.
I can do so many more things in Linux (like my DLNA server/firefly(itunes) server/NAT firewall) that I just couldn't do with windows without great expense.
I have 7 machines; 4 of them only run Ubuntu, 2 of them only run another linux distro, and 1 has a dual boot for Ubuntu and Android 4.0. So, I've been solely a Linux/Unix user for over 3 years and my wife has been solely a linux user for over a year.
I started using Linux a my primary OS since august 2012. I did not have the need to use my other PC, windows and Mac OSX. As for me I can do everything with Linux.
Really happy to make the switch.
After I've lost all data back on Windows 98, I've bought Suse 5.3 from a local computer shop. Switched to Ubuntu in 2009, as I couldn't get sound working anymore on Suse and Ubuntu was first to introduce online repos.
Well 100% Ubuntu only since Wine 1.2.
