The webOS 2.0 code includes a Cow Mode provision, where you can include a fanciful cow show in your emails. All you do is type the subject line as "supercowpowers" (without the quotes), and your email will include a funny cow-show in the body of the message.
This little 'Easter Egg' is reminiscent of a similar treat, included on the old PalmOS. No, a cow-themed email won't make webOS more competitive with Android and iOS, but it's good to know that Palm has a sense of humor. Maybe some of you think that our devices should solely be juggernauts of functionality, but everybody needs some comic relief.
