Thanks for the counsel oh great sages.
When my machine returns from Apple, I'll do the install.
Alas, two days ago, my HD started making the dreaded clicking sound. And, of course, all went wacko from there. As to the warranty, I was three weeks out of date. Not to worry says Apple, the replacement is free. And, the old 250 GB HD is being replaced with a 320 GB. I would say "woot", but I am about 45 years beyond that, so I'll just sing their (Apple) praises.
