I have a late 2008 MBPro and with software I've spent well over $3500.00 on it, not to mention all of the other Apple products we own. (I don't even want to add it up!) Since installing Lion and switching to iCloud my MBPro has been a mess!!!
It started the with the same symptoms other people have complained of. Certificates marked untrusted started showing up. Then the iCloud keys started multiplying. Then I couldn't wake my MBPro from sleep. If I dared close the top, it took a long time for the spinning wheel to stop and the MBPro to start, until pretty rapidly, it wouldn't start at all. I had to cold boot it to get it to work whether I was starting up from sleep or having turned it off altogether.
I reformatted and reinstalled Lion, set iCloud back up from scratch. Quickly the first symptoms started showing, and this time around I suddenly was not allowed to save my own documents and had to input the admin password for every change I made. Then it still didn't want to let me save so I had to keep making duplicates to save! After that, websites I have accounts for started rejecting my entire MBPro, completely. Not all of them, but increasingly numbers of them. Finally, the entire machine went belly up and I couldn't even start it from the original operating system disk to reformat it again!
Finally one command did work so I could reformat, but it wouldn't let me install anything but Lion. (I wanted to go back to Snow Leopard). The only choice it gave me was Lion and it was that or a blank screen, so I went with it, again. Now it is working, but sure enough, the problems are already creeping in, and now my spouse's MBPro, purchased a few weeks after mine, is starting to have the same problems. (He installed Lion later than I did. Note: I waited a few months before I made the switch to Lion in order to avoid unnecessary bug hassles.)
I'd been planning on buying a new MBPro with a larger screen and the top specifications, which will run me about $3600.00, and I would have done so by now if it were not for all of these problems. The entire reason for switching from Microsoft/Windows in the first place was that I was so sick and tired of spending inordinate amounts of time fixing problems and having to reformat three times a year. I don't know whether it is only Lion or Lion and iCloud, only now I am back to life as I knew it with Windows, but I've paid a Heck of A Lot More for the agony. I am a Very unhappy customer.

I forgot to add that some programs, especially Aperture, have become a pain to use too. Slow, choppy, freezing, and crashing.
