Article pagination... good or bad?

For the MSDN Magazine Web site, one concept we frequently revisit when thinking about how to improve it is that of article pagination.  Some of the articles in the magazine are relatively long, and on the Web site, each article shows up as an individual page, which can mean quite a bit of scrolling when reading an entire piece.  In scenarios like this, other sites frequently use pagination, where they divide an article up into some number of pages, and rather than scrolling, you click "next" or a particular page number to move around.  This is a behavior we've always decided against, preferring the one-page scrolling approach, but we're now considering pagination again, and your thoughts on the matter would be appreciated.

Which style do you prefer?  Is pagination something we should add to our site?  And if we do, should we provide the option to read the content either way, or would you always prefer one versus the other?
