I am getting interested in possibly buying one of these. Can anybody
tell me where would be one of the best places to try this out? If I
just stop at a Best Buy or Circuit City are they likely to have them
in stock and allow me to try it out?

Also, I may be interested in a device like this to use with a
Slingbox, but I gather that it is not compatible with Slingbox, at
least yet. Does anybody have any idea if this might be a suitable
device if the software issues were to be worked out?
