→ My kind of feature checklist
∞The latest technology I've been learning is Palm's SDK for webOS, Mojo. My first impression is that it's a great platform and Palm could do a great job of 2.0 if they cut down on some of the verbosity of gluing together the UI. I have learned to like JavaScript over the years as I learned that despite its warts there are good parts too. If you squint just right you can see that it's scheme with Algol syntax. HTML and CSS are what they are, but with WebKit running the show and only a single engine to target it's not that bad. I've gone from Eclipse to Emacs for the coding itself and highly recommend Emacs for Mojo development. There is nothing that I miss from the Eclipse or Komodo Edit thanks to the fact that Mojo uses open languages and standards.
As far as actual development goes the Mojo documentation steers you towards a combination of Eclipse, Palm's Mojo plugin for Eclipse, and the Aptana Studio plugin. My editor of choice is Emacs but I decided to give it a spin just to get started quickly, how bad could it be? I'm not going to get into details but I will say that I don't think I'll ever use Eclipse for anything; it's far too sluggish and provides no compelling features for the languages that I use. I tried Komodo Edit and it was significantly better but still not for me. Emacs is great for editing HTML, JavaScript, and CSS so all I really missed from the IDEs were the shortcuts to package, install, and launch apps in the emulator. I headed over to the Emacs Wiki and downloaded Jonathan Arkell's Mojo support for Emacs which provided a great base to get started with. There are wrappers around (all?) of the Palm SDK commands but it needed a bit of work to make it just do what I wanted with as little input and thought as possible.
