Exactly. You should have seen the Leopard nightlies. The top bar translucency was off for a while and it was basically non-functional. The dock would crash regularly, etc.
The lion beta was a nightmare as well. I have never seen an os with that many kernel panics (definitely not custom driver related), lag and just random flakiness. And safari was just in a league of its own - although I do miss the tabs on top.
