I started this course today (through Coursera) and so far it's great. Looks like they're using the Khan Academy software for the practice exercises and the videos are excellent. The instructor is high-energy and sort of eccentric and it's a real hoot watching at 1.25x speed. My only gripe is the textbook: it looks slick, but the weird Greek letters start on the first page and the prose is...laconic. The rest of the course materials seem geared specifically towards totally green beginners; the style of the textbook is a little divergent.

I agree this calculus textbook reads more like an introduction to analysis textbook for sophomore/junior level mathematics majors. Complete with problems one step away from asking your to write proofs for the problem solutions.

While I can't wait until some higher level math is available online. I don't think that's what they're going for here.
