Richard S,

At the time that I wrote this review, VIZIO was not listing a 37" 1080p for sale. A couple of weeks later, they started.

I can tell you that none of the VIZIO 2008 models have a USB or an Ethernet port.

If are referring to the 37" 1080p model is the VO37LF, I reviewed the 47" version here:

Since I don't see anything different in the specs for the VO37LF, my review of the 47 should apply to the 37.
