3G does not require a better CPU. Wireless is all handled on the GSM/CDMA chipset, and simply acts like a modem or other serial device to the CPU. The screens are identical between the two as well (what other screen would iRex even get? The two models are less than a month apart in release, and only e-ink even makes a 768x1024 16-greyscale screen at the moment).

The switches are all in the code. You'd have to install say, the 800SG firmware into the 800S or vice versa to change the device between the two models. I can say with certainty that doing so won't change the performance of either one.

If you actually read the complaints, it isn't about speed of the 800S that turns people off (so why keep bringing up a better CPU?). It is about the lack of features compared to the relatively high price of the device. It's the value per dollar that doesn't make the 800S look so good. The best claims are backed up by evidence, and the stuff you are guessing on isn't backed up by evidence (anecdotal or otherwise). The evidence is right here in this very forum, and I've not seen anyone make any sort of comment that would back up your hypothesis.
