Mozilla OS Dual-boot Android

[gtg93]

Has anyone given Mozilla OS a try yet? They've recently done an update and it sounds like they're getting somewhere with it:

Firefox OS update adds performance, polish to Mozilla's webby mobes

 

More specifically has anyone tried the dual-boot option yet? I'm thinking of giving it a go on my SGS2 and wondered if anyone had any tips or comments on it?
