Android L有人刷了吗，求试用感想

This Thread is intended for People you have installed Android "L" Preview and have not tried to do any sort of customizing to it. Also for the people who are coming from a clean wipe. With the other thread getting to ridiculous lengths already I find it easier to have a thread dedicated to just this issue. Please keep all comments on track and hopefully this doesn't get closed.
