Javascript everwhere: PhoneGap and Node.js (and no Eclipse)
Got into PhoneGapApache Cordova a little while back. First I got into Titanium Appcelerator, thanks to my friend Silvio. But Titanium was all Eclipsy and then when I wanted to do some coding in the train I found out that I needed to be online to code in Titanium. I do have Ben Internet in the Netherlands and Mobile Vikings in Belgium but it's not always working amazingly in a moving train and this restriction was a tad bit too much.
