I've got a Canon SX700 HS that I love, but you really make a great case for the Canon G 7 X Mark II.
I also wanted ask if you had any deals worked out with schools to provide your courses as part of a curriculum development program. Teachers/Instructors/Professors are turning more and more to digital content creation and we're getting functional advice, but not always great advice like you're providing here. I'd much rather take your course and get credit, so I hope you would consider looking into packaging a professional development tutorial for educators.
