Re: Mac OS X Lion
I'm not in a hurry. I'll probably upgrade my home iMac in a month or two, but as far as the Macs I manage at work, I'll take my time. Everything's working fine on Snow Leopard and there's no compelling reason to change yet.
But for people that are in a hurry... my usual advice is to first do the research: see what other "bleeding edge" users are saying re: compatibility and potential problems.
Then, do your install on a separate drive or partition. That way, if anything goes wrong, you can always fall back and boot off your old system. Once everything seems to be working, you can clone the new system back to your original drive/partition if you like.
You will never lose any time or work if you follow my advice!
