Just updated a couple weeks ago. Had to wait till I could spare some change for a new HDD, as my MBP's OEM 120G was tapped out.
But it's all good, so far. I installed the drive (320G/7200), restored from my TimeMachine backup, updated to SL. Only "issue" was it told me it couldn't copy my users, but a quick run through Migration Assistant cured that.
Even cloned & expanded my BootCamp partition via WinClone!
SL does seem snappier, but some (or all) of that could be the 7200 RPM drive. But also, the machine seems to run cooler, with better balance between the two cores.
Now if onlly I could get rid of the last vestiges of PPC Code. I've got some apps that I can't update just yet that are still PPC, but there's something that runs every time I boot that uses PPC code, and I can't seem to figure out if it can be run with Intel code or not. It's not something running when I log in, but something in the OS. I've done searches, and it appears to be important, but, of course, I can't recall the name right now!
Merry Christmas & Happy New Year!
