True. Doesn't address the userstylesheet problem though.

Also, sending prerendered pages with inline styles causes a bandwidth problem. Your prerendered page is probably dynamic and uncacheable, but your stylesheet isnt. By using inline styles, you send tons of repetitive uncacheable styles over the network where you could have just used a stylesheet.

If you need the power that a full general purpose programming language gives you for some of your stylesheet, go ahead and use inline styles where needed, that's why they exist. But there's no reason that you should then decide that all of your styles ought to be inline.
