I'm writing this on a MacBook pro I picked up this weekend. I love it. It's not the fact that it's now powered by the Intel chip, it's not the fact that it replaces the Risc architecture of the powerbooks and finally makes it price competitive with comparable win32 machines. I love the fact that converting my old iBook took a total of 45 minutes...It moved everything to the new machine; files, settings, user accounts and APPLICATIONS, fully registered.
The process was really simple; boot the new MacBook, connect the firewire cable to both machines (old and new), reboot the old ibook holding down the "T" key, DONE. So for those of you that dread losing data, don't fret.
The only downside to the MacBook is the battery life. A dismal 2 to 2.5 hours... The iBook had a better battery life. Overall a great purchase.
