Yep. Especially so for those who sell flash chips, by an amazing coincidence
The power saving point is fair -- flash does take less power than RAM. But
if you're _that_ short of power, you're likely to be using expensive (but
low-power) SRAM, and have the rest of the system so tightly specified that
you'll be more likely to be using something like eCos on it, not Linux.
With the chips available today and in the near future, XIP, at least for a
writable flash chip, makes virtually zero sense on Linux. Anyone who tries
to tell you otherwise is either on crack, trying to sell you something, or
