to update or not to update to OS X Lion, that's the real question. I have found my macs never run as well with an OS other than the one they shipped with installed.

Odd. I've never had a problem with upgrading Macs, at least to the next 2 gens of OS's. Then again, those upgrades usually happened at the same time as RAM upgrades, so maybe that's a key point. Still, this OS is very track-pad heavy, so remember that if you do upgrade, you'll probably be buying a track pad soon.
 
Updating mine now. some people say their system performance seems a bit snappier
 
I'm worried about compatibility issues with my music software. Plus I don't think it's worth the $30 just to have shortcuts to the programs that are already in my dock.
 
@quentyn my 2010 MBP not only feels snappier, but it runs significantly cooler. CPU management seems to be improved. FWIW.
