I've only used it for a week but I love the 85mm 1.8.
Pros:Looks cool
Nice quality optics
The USM can focus faster than my eye!
Feels very solid for the money
The bokeh
Full-time manual focus
Cons:Some purple fringing wide open (not apparent until heavy crops are performed)
A little play in the ring (forwards and backwards) This is normal, and not really a con
Minimum focus distance 0.85M - not really a problem for me
Bad hood mount (+canon doesn't give you a hood

)
I am being very picky but it was very easy to list the pros.
After using this, I do not think I will ever purchase a zoom lens.
