finally, i couldn't wait to see some preview videos, was sad that iOS 7 vids were up fast but not Mac OS X ones.

indeed, it looks very responsive compared to what i'm experiencing on my system. and my system is more equipped than the systems i've seen in these videos (i5's, 4gb Ram etc..)

i'm on late 2011 MBP i7 / 16GB Ram / Samsung SSD830
