My 17-inch Apple PowerBook G4 has served me well for the past 3 and a half years. As new, faster models appeared, I thought many times about upgrading, but even the current models look essentially the same without any significant changes. I love the screen real estate, but with the addition of an external monitor to the setup, the advantage of the large screen (especially when I was at home) was limited. The cost was a heavier, bulkier computer when I was not at my desk, which has become increasingly common. I thought about upgrading to the MacBook Pro released earlier this year, but early models were reportedly buggy, and the design was still quite similar to my now dated model. The arrival of the latest (and quite inexpensive) MacBook, however, has persuaded me the the time to upgrade is now. The PowerBook, like many of its predecessors, has now been eBayed. Farewell, my friend.
