of Tiger on Saturday and, after doing a full bootable backup I installed it as an upgrade on my main drive. Unlike others, I have always had a very good experience with upgrade installs, and this time was no exception. Everything works flawlessly.

My main question now has to do with Mail. There are two new, and deeply related, features in Mail – the integration of Spotlight, Apple’s new search technology, and the Smart Mailbox functionality integrated directly in Mail. So, the question is this: is it time to ditch all my Mail folders and keep everything in one mailbox (per account) and just use Smart Mailboxes to sort everything out on an as-needs basis? It seems silly to keep things artificially segregated when I don’t have to do so. At the same time, I have tens of thousands of emails going back to 1994 or so in my system and I wouldn’t want to have performance issues with keeping so many emails in a single master list. Any advice?
