The Pi isn't that expensive: if you're after finding out about RISC OS 5 and
how RISC OS is now supported on new hardware, buying a Pi is probably a
better bet than something based on a Beagle or Pandaboard.

It might if it has DVI: you'd need a HDMI to DVI lead, and not an HDMI to
HDMI lead.
TBH, you'd be better asking that on the ROOL forum (yes, I know) as that's
where you'll find the most people who understand the graphics capabilities
of RISC OS 5 on the Pi. The forums aren't great to use, but it's where the
knowledge is and you can easily search them for stuff.
Once I'd decided to make an effort to get on with the forum, it turned out
to not be that hard to use. I find reading the recent posts list is the best
way to keep track of what is going on, then follow threads off that.

What do you want to do with it?
The bottom line is that RISC OS 5 on the new hardware (the Pi or the
Beagle/Pandaboard) is just like RISC OS 5 on the Iyonix, which in turn is
very much like RISC OS on a RiscPC or Virtual Acorn. The hardest bit is
getting the card image in place and booting -- on the Pi that's done for
you, so that you don't need to worry (see below).
There's obviously the issue of ARMv6/7 compatibility for software (just like
the problems when the Iyonix went 32-bit), but since the Pi came out a lot
of former developers seem to have come out of the woodwork and are working
on updating their code (even if it never went 32-bit 10 years ago).

There's a certain chicken and egg situation, yes. However, it's easily
resolved as ROOL will sell you an SD Card with a RISC OS image on it for a
tenner. If you also get yourself a couple of blank SD Cards (or more) of a
suitable size, then you can use that card to put images onto the others. As
long as you always keep one card 'safe', then you should be OK.
RISC OS can also self-update now, AFAIK -- as long as you always have
another bootable card to hand, then even if that screws up somehow then
there's a fallback.
The nice thing about the Pi (and Beagle/Pandaboard) is that because the
RISC OS 'ROM' lives on a removable (Micro)SD Card, swapping ROMs becomes
trivial. You can therefore have several different systems on different
cards: a "stable" one that you use for serious stuff, and "bleeding edge"
ones with the daily test builds on to experiment with (if that's what you
want to do).
