mine had very hot cpu, and slow software about 2-3 days after the upgrade, then all went back to the level before upgrading, i even feel safari faster, only pity is the cord for ml is quite buggy. maybe you can wait a couple of days and see.

after around 2 days, mine got back to normal. Looks like the machine takes some time to get used to the new Lion? However, I found another issue with the antivirus-Sophos, it always disappear after update, another common problem for new lion users. May have to wait for next 10.8.1 then.
