There's also:
- 320 & Up by Andy Clarke, which is based on a mobile comes first design (so, it's good for that) - http://stuffandnonsense.co.uk/projects/320andup/
- and Gumby, which got some really good reviews - http://www.gumbyframework.com/
I can't really help as I'm still too yet to try one of these responsive frameworks out. I too wish to know the pros and cons of each.
