I am using Linux as a desktop system for quite some time now. Starting with a distribution of SuSE dual-booting on my Windows 95 gaming machine some years past, it eventually became my main system, although I also had short stints with Windows 2000, Windows 7 and Windows 8.1 (which I think is a really good operating system).
Evolution
I prefer Evolution as client for my mails, addressbooks and calendars; although I tried other clients - claws, Thunderbird, geary, mutt - I always move back to Evolution. Switching was a matter of functionality most of the times. The look and feel of Evolution was always great for my personal taste, but when I changed from local calendars and addressbooks to online services or from POP3 to IMAP, evolution fell short of other clients. Everything was implemented rather fast, but sometimes, things just did not work properly. Calendars would not sync, buttons in Evolution just did nothing or at least not what they said.
