I have to agree - I let it upgrade my Nexus 5 (a fucking Google flagship product) from 4.4 to 5.0 several days ago. While I haven't experienced the same problems zebo has, I have had a lot of screen tearing, and when idle, the battery drains fast.
Can I roll it back? Noooooooo......
Wait for at least the first update.
