I see a lot of this sentiment amongst developer friends but I never could relate. Its not that I'm against it or something but it just doesn't move me personally.

Most things I create in my free time are for my and my family's consumption and typically benefit immensely from the write once run everywhere nature of the web.

You can launch a small toy app on your intranet and run it from everywhere instantly. And typically these things are also much easier to interconnect.
