I love the 12" Powerbook. I do. I'd be first in line for a replacement that had its footprint. But it's beginning to show its age, it runs the apps I want it to run, but it's not as snappy as the new MacBooks I've played with are, and I'm prepared to upgrade to a MacBook. I know there will not be a revision to the MacBook in the short term, but Snow Leopard is possibly coming soon. I'm wondering how much of a hit in value the PowerBook will take when Snow Leopard comes out and the PowerBook is running an outdated OS? Specs if it helps: 1.5Ghz, 1.25 GB Ram, Superdrive, Leopard, flawless physical condition, battery holds about 2 and a half hours.
