I use it, thanks to Xander314. Don't bother learning SDL nowadays, Its non-object-oriented nature is a thing of the past ^^
SFML is VERY easy to use. Follow the tutorials on here and you'll see: http://sfmlcoder.wordpress.com/
And documentation here: http://www.sfml-dev.org/documentation/
Agreed. Also, SFML uses hardware acceleration, so it works a lot better on newer computers.
I found these tutorials REALLY helpful because there is no "spoon feeding" and they help you get your hands dirty :D http://sfml-dev.org/tutorials/
