I'm using the latest nightly build of Camino, and there are some significant improvements.
1. It's even faster than Camino 1.0, which I was previously using.
2. It now renders text with Cocoa, so pages look much better (like Safari).
The main downside, as usual, is that textboxes still aren't real Cocoa text boxes. Spellcheck seems to work in that misspelled words get underlined, but you can't right-click them to see spelling options or bring up the dictionary.
