I think we have two competing desires.

one is to have a nice powerful device for those people who have fast connections 
and for us to experiment with.

the second is to have a 'home' device.

using a 3800 or similarly priced ($100-$150 USD) device that's readily available 
is very good for the second category, the question is if we can find one that's 
powerful enough for the first.
