Congrats on a better distro guys and gals.
I was happy with 11 until an update made my Synoptics touchpad have a mind of it's own on my old Compaq Presario 2200 laptop.
Drove me mad and despite reading about speed issues with 12 reluctantly switched across and can only say it's much better.
Faster, smoother, and everything seems to be running very well.
I notice the subtle changes been made and it's looking more polished.
I guess I'm a bit slow on doing this, but I must pass on my thanks for a job well done.
