The rumormill is churning away. Of Apple rumor web sites, I tend to prefer www.9to5mac.com.

The nutshell seems to be that everybody's expecting something this summer, and there are a small number of supporting factoids that are used to corroborate this. If nothing else, Apple had lines around the block last summer. They may want to get a repeat performance this summer. They're going to need to keep innovating anyway, as other vendors have now finally gotten the clue.

I, personally, was speaking to a Motorola cell phone guy who was talking about Android and how they're all excited to be building new stuff around it. Sprint has announced that they licensed a patent, not from Apple, that claims to cover visual voicemail. One way or another, iPhone-ish features are going to start appearing from other vendors.
