I was a huge fan of famo.us until just now. Testing in iPhone4S, most of these apps are super jittery (never continuously 60fps) and unresponsive to touch in the browser, especially Yahoo Weather, which looks to be the only one complex enough to resemble a full app.
At best, this is a very impressive "mobile web app" framework NOT a native replacement. I would never trade up obj-c for cordoba/js if this is the kind of inconsistent performance users will have to deal with... and btw I love javascript.
I think steve is a phenomenal entrepreneur but may have built this launch up way too much. Without their native wrapper and MVC this feels like it's going to be a few years before it can rival native development.
Sorry but Steve is hardly phenomenal. All his talks are just hype and have little content. Have you attended his talks face to face? So much talk and so little actual stuff.
EDIT: compare him to the other Steve. Jobs only ever announces stuff that is pretty much ready for shipping. Now that's phenomenal.
