I really like Foundation based on the same points you raised.

It does support IE8, minus the responsive stuff, it's < IE8 that it doesn't (http://foundation.zurb.com/docs/support.php), and that's a deal breaker for me and why I've never used it since most of the sites I build still get around 10-12% from IE7.

You could use the older version of Foundation, but that doesn't appeal to me either.

I use foundation at work. We have the rule that "make the site look fine in IE7", where it has to work but it doesn't have to be perfect.

You can use foundation 3.1 with the htc boxing fix [1] that fixes the grid problems with IE7.

I love use foundation over BS, since BS (to me atleast) is more of a UI decision, where you build your site from scratch with foundation).
