I doubt this applies to all that many people in these forums, but I’ve published a Sugar for developing apps for Palm WebOS devices (like the Pre or Pixi) in Espresso:

I’ve been developing a WebOS app in my spare time over the last couple months (here’s more info on my first WebOS impressions), and writing the basics of this sugar was one of first things I did. It’s still pretty amazing to me that it’s possible to develop rich mobile apps using web technologies, and a dream come true that I can do it in Espresso rather than Eclipse like Palm recommends.
