Enterprise Mac's Tom Yager posted about his recent transition from a PowerBook to a MacBook Pro using Tiger's integrated Setup Assistant. Using Setup Assistant one can easily transfer old data, settings, applications and more to a new Mac over firewire. His migration took a little under two hours to transfer 60GB of data rather painlessly.
What I found insightful with Tom Yager's post is that with Rosetta one can still use most old PowerPC applications without having to search for upgrades. This makes switching (or cloning) to a new machine a hopefully trivial experience. Have you had a breezy time of upgrading your Mac using Tiger's built in Setup Assistant? We're all ears.
