Highlights from the comic (drawn by Scott McCloud! The Tufte of comics!):
- fully open source
 - separate processes for each tab (no more entire browser crashes from crufty javascript on one of your 18 open tabs!)
 - new v8 javascript virtual machine - with hidden class transitions, dynamic code generation, and my personal favorite, precise, incremental garbage collection
 - goofy 'tabs on top' user interface
 - creepy omnibox
 - new tab page = home page based on your most used/trafficked sites
 - 'incognito' porn surfing mode
 - some other random security stuff that bores me, but which will be another strike against malware etc. Sandboxing - i'll believe it when i see it.
 - Windows only right now, of course (sigh). C'mon, OS X is where it's at! What about platform independence!?!
