Indeed. Shepherding people through the carbonized rubber reset ritual
was by far the most extensive support issue on #qi-hardware. What's
nice about the SoC is that it has a USB boot at all and doesn't need
JTAG or such. But I'd look into including something like IDBG to take
the pain out of reflashing:

Not having a host port was a constraint coming from case reuse. Not
even having access to the D+/D- signals (so that one could make a DIY
solution) was clearly an oversight.
Modern SoCs should all have OTG so add a Micro USB AB receptacle and
you're good. Maybe even make that two. Make the second a BOM option

Yeah, wireless is no longer optional these days. Wifi is still a
shady area and getting an embedded-friendly chip/module to work
may need a bit of work since the ones with an SDIO interface
often don't have Linux drivers.

Hmm, that would depend on whether the SoC has that. Some do, some
don't. Of course, even the lowly the Ben can still do this:

I never tried to develop locally on the Ben but I'd be surprised
if we didn't have packages for make and gcc. I know we have vi.

I think that was another major oversight. While significant effort
was put into maintaining the distribution and to make Debian
packages of most of the host tools, the cross-development
environment fell through the cracks. I don't see a reason why one
couldn't make a Debian (or such) package, though.

Funny, I don't think I ever used an emulator for any embedded
system ;-) I could imagine it would be useful for regression

No, LESS Flash ;-) Have a memory card (uSD) and never worry about
the chips on your Nanonote getting old. Also for RAM, it would
probably be more difficult and more expensive to have 32 MB than
a much larger size these days.

vi ? :)

They're great. Huge capacity, easy interface, a dream to source
(you don't even have to do it yourself), and so on. Plus, the
interface can be readily reused for experiments. All you need is
a little UBB ...

You get that for free if you have Linux :)

Yup. The form factor is part of what makes the Nanonote special.
