Reply to Any logic pro users?

Ok i used to use reason 4 (tried fl never liked it) about a year ago moved on to ableton live and i love it but i mainly use it for ideas/performance and would prefer for making tracks to go back to a what you would class "normal daw" layout.

i just got a MBP and have allways been interested in logic as a program

so a few Q's

whats the learning curve like in logic?
whats the main difference between 8 and 9

and if anyone could point me to some videos that might help would be great all so,cheers.
