Adobe has released Adobe Reader for Linux, version 8.1.1. What's important is that it now fully works with GTK 2.0, so the interface is consistent with the rest of the GTK apps. It has subpixel rendering, unlike every other PDF reader out there for Linux (Poppler has an experimental patch that is very bad. Someone told me kpdf has this feature, but the one from the Feisty repository does not). Read an article about it.
The downside is that it's bloated and slow, but I would trade fast response to a slight lag for superior text rendering any day. This is wonderful for Linux users with LCD screens.
