A desktop, a laptop, an external hard drive, an iPhone, and me. How should I sync my iPhone? I've got a 16GB iPhone arriving tomorrow, my first one. Now I need to figure out what to do with it. Our household consists of an iMac that's primarily my husband's and a MacBook that's primarily mine. I'd prefer to manage music, apps, etc. on my laptop. However, the external hard drive that houses all our music is usually connected to the desktop, and it would be impractical to switch it back and forth between the two computers. With my old iPod, which after tomorrow will be my husband's iPod, I didn't have a problem just syncing it with the desktop, but apps and calendars and contacts complicate matters and I'd rather use my own machine.

I'm sure there a few different ways to do this. The best strategy I've been able to come up with is to get a $30 16GB USB drive and point iTunes on my laptop to the USB drive, so apps and podcasts save there, and periodically swap out the music. That seems sort of clunky. I can access the iTunes library on the laptop over our wireless network, but that doesn't help with syncing, right?

What other options should I consider?
