Cheaper and faster. But remember who Jared works for :)

Seriously though, XIP is a win on power -- it doesn't take constant
application of power to keep your data in flash. If you start comparing
prices of SRAM and flash, the game becomes a little different.

Of course, if you're _that_ concerned about the power budget one has to
wonder why you're using Linux, but then JFFS2 runs on eCos too...
