Calling it unreliable is charitable in Diablo on the N810. I've got a fairly clean install, stock kernel, minimal apps, and fennec 0.4:

1. Won't load www.cnn.com without crashing utterly
2. Will read mozilla.org site for at least a few pages before crashing utterly
3. Is slower than microb - takes about 50% longer per page
4. Jump scrolls rather than flows (page scrolls on finger release)
5. Won't access the ITT forums (home page is ok)

I had about as much luck with their alpha release several months back. This software just isn't ready for the public, and testing it is painfully frustrating.
