One problem that some of us have is that we are _hobbybists_ in this
field,
and therefore have a limited budget.  Any savings is considered good,
and the
P4/P5 pricing is excellent for many of our intended uses.  We also often
are
unskilled in the hardware side, so some of the hacking that might be
used to
a) build an HMD from parts or b) fix an off-the-shelf HMD with interface
difficulties is beyond our immediate skills.

I've missed these 'try before you buy'  offers....could I actually get
an M1
shipped to my house for a test drive, or would I have to go into a
retailer?

But all those still, even on a desktop machine, draw very little power
compared
to the monitor, and there has been much less work getting display
technology
down as much in power, up as much in durability, and down in size, all
in a
pacakge the consumer can afford - look at the flat-screen displays for
non-laptops;
still in the $1K range (AFAIK).
