PALM

By now you know the row: Palm co-opts Apple iTunes access for its new Palm Pre smart phone without permission and hails the electronic trespassing as a key selling point for iPhone users to switch platforms. Apple vows to protect its intellectual property and earlier this summer issues an "update" to iTunes that cuts off Pre users from syncing their devices to iTunes. Then Palm issues an update of its own, re-opening Pre's access to iTunes. That's the 30,000 foot perspective, anyway.

But as you get a little closer to the issues, they get far stickier, and far thornier, for both Apple and Palm.
