They've now forced all their users to the 'new' interface,

Absolutely true. Even on my fastest machines I've taken to using the mobile version. It's small, clean, fast, and you can do nearly everything on it that you can with the main site.
Except that the complaints about Twitter's new interface are all related to Javascript performance, and have nothing to do with CSS. Their toolkit release was all about CSS.
