I took the 820 for a test drive today and was very impressed.
Like any new machine, I know there's bound to be a learning curve before it's totally comfortable.
I'd be interested to know what everyone sees as the best feature(s).
Also, to know what the dislikes have been ... or where it is a fussy-pants.
And yes, some of those things might only be intermittent til you are more familiar ... though I think it's important that we know the worse that is to come!!
