Yeah, I think the benefit of the Qualcomm platform is the graphics
situation upstream, and they also come with a (native) bootloader that
makes more sense for those not used to the embedded ways of booting.
Sigh, I really wish ARM would come to the table and start working with
upstream on their Mali drivers.

About 845; it looks like there's mostly announced products and none
are shipping yet, so most people with knowledge probably still need to
be tight-lipped about details. I do look forward to seeing some of
these products coming out and what people will do with them. The fact
that secure boot can be turned off on them through regular settings is
promising.
