The year of the Linux desktop is right now, if you want it to be. For me it was 2007 - and watching the evolution of Windows since then has been a continuous validation of my choice.
If you want to use Linux, use it! It's ready, and IMO has been for some time.
(And just to be clear - choosing otherwise is OK too! I don't intend my enthusiasm as zealotry. Folks making an educated decision to stay is totally valid.)
