[Sephiroth]

If you look at the attached image (block diagram of the Broadcom Gateway chip in the SH), you can work out for yourself how many offered functions are not taken up in it's VM implementation.

Additionally, its wireless is weak because (IMO) of the preference for "sexy design" over sensible practicability. External antennae would make an enormous difference or at least the plug-in ability to do that.

So yes, except in modem mode, the SH is at best no better than a get-you-going device and at worst a piece of router junk.
