You will love it. I have gone from a 5.25" Newt on a wabbletronic EQ2 mount to an 8" dob and then to a 12" dob. Each upgrade has brought me more joy in the views afforded.
A 10" is a great starting point as there wil be hundreds of objects easily found, it is easy to use and setup. Try to get to a dark sky site or a star party (Qld Astrofest?)where it will really shine.
The only thing you will need to learn is collimation but once learnt is is really easy to do
