Yeah, I am a fan of Arch on the desktop, but the P1 runs Nvidia's P1000 chip and Arch doesn't seem to like that, so I went with Ubuntu+i3 for now. Updating the firmware first is definitely critical, as you could brick the machine otherwise.
I'll echo my disappointment in battery life, although admittedly i3 and xfce defaults are probably not doing me any favors here...
