I asked this on Tested, but I thought I'd ask here as well and get the mac gamer people to answer (do you exist?)

So I bought my uber macbook pro around 8 months ago. It has an i7 processor clocked at 2.66Ghz, 8GB of ram, and so on... It was running smooth as a can be until I downloaded the Snow Leopard 10.6.8 update. For some reason, my computer which usually boots in 20 seconds, now started to take LITERALLY 5 minutes. After research I found out that 10.6.8, is prep for Lion. So I did a clean install of Lion. Now it instead of taking 5 minutes, it takes 2 minutes + to turn on... Also Lion is buggy as shit. When computer goes to sleep, upon wake up, Chrome crashes, and everything becomes unresponsive. Also, the dock can't fucking seem to remember what I want it to have. Everytime it restarts, it removes some of my dock icons... like Safari...

Does anyone have any idea what's going on? Is my computer being weird, or is Lion truly a piece of shit from a technical standpoint?
