I've based this opinion on my own experiences with Raspberry Pi. It's
as reliable as you can expect from $30 hardware - if you're lucky your
configuration will work perfectly, but if you're not, you'll find a
lot of annoying problems (for me it was communication with USB HDD
failing after ~20-30 hours, freezing the system, firing watchdog
reboot and putting the board into reboot loop). However, I have an old
B variant - the new B+ has some tweaks, so it might work a bit better.

Anyway, Raspberry Pi is not optimized for battery - it's supposed to
be powered by USB 5V, which is a bit suboptimal for batteries. CPU
power management might not be fully used as well, especially with it
being actually a side-processor to the GPU which runs proprietary blob
and controls the ARM CPU. Hence my opinion about it being a nice,
cheap platform for a project made out of hobby, however, I believe
something like a BeagleBone would be better for any actual project
that would like to produce something.
