And as for their passivity; they've already countersued in every venue Apple has sued them.

I'm pretty sure that Apple won't sue over a Windows tablet either.

Thankfully, Apple only sues people who profit off of this.

On the other hand, Apple sues too much over vague patents.

Apple sued the companies for copyright infringement in March 1988.

That was my first thought also, Apple suing because they look like the Nano.

Microsoft and Apple have sued others and continue to do so.

Apple also sued the Hewlett-Packard Company on the same ground.

Apple did not sue the sites directly but sought to subpoena their e-mail records.

Makes you wonder why Apple is suing them, eh?
