There's been lots of improvements in the DOM, those slick CSS3 transitions are actually hardware accelerated with OpenGL, lots of GUI front-ends don't event have transitions in the first place. I wouldn't rely on Javascript for crunching data though, the "slowness" you talk about? Mostly stems from that. Otherwise, for display, it certainly is a great tool with lots of open source components.
In my experience performance issues are either DOM/redraw related, or old versions of IE. Javascript performance and download speed are nonissues if you do it right. Send data in a format that compresses well and those 2MB turn into 200K. Add caching and background loading... Etc...
While some are still blaming the hammer, I blame the person trying to hit the nail on the head with his eyes closed.
Yes. Unfortunately many Javascript programmers don't know how to do it right... Or their superiors halt development before performance tuning because it "works".
