It's
already here ;-)
The macbooks are sweet. I would want one so bad if I didn't already have a powerbook. The only downside is that certain apps, including Photoshop, haven't yet been updated to run natively on the intel chips, which means a performance hit. But that's only a temporary thing; the next version of PS (CS3)
will work at full dual-core intel speed.

In the meantime, I suppose it's possible to boot the windows version of PS and run it there. But yeah, the macbooks are sweet. I would recommend one of those over the camera.
