I have to say....this son of a gun is FAST!!!! Running it on my Neowin-Donated Lenovo y510p, and oh my GOD this thing is faster than the day I opened the box! Cortana is iffy, works every other reboot, and boot times are garbage, especially for a 16GB i7 system, but once it boots, and I click something.....oh my gosh....I'm really happy! Wish as an insider I'd have not given up, but the lock ups were a showstopper for me. Now, it's amazing!
