In reviewing these articles, it appears that the only real advantage of this technology is hardware footprint, but it still works analyzes signals serially except now the issue is noise and distortion comes into play. So when is the next technology coming that can take a signal and process it in parallel?

SNR is not useless, but should be properly treated. One of good measures for ADC noise performance is dBFS/Hz, which is power ratio of full-scale harmonic signal to noise density. Consider this article (sorry not in english), but pictures and equations are clear. Note that this is status quo of 2004 year, nowday ADCs are about 4 dB better: http://www.elektrorevue.cz/clanky/04050/index.html

Great follow-up to Part 1, and a nice job explaining which specs matter in SDR and why.
