Just thought I'd let anyone who hasn't heard already that the first alpha of Opera 10 is out. It passes the Acid3 test and also boasts better speed, rendering, security and so on. I'm actually posting this with it right now from my XP drive. It's quite decent, IMHO.
I haven't checked if there are any linux builds yet (probably are). Anyways, just giving a heads up for any Opera fans out there!
