depends on proprietary firmware (or binary blobs?) inside of it?
Yes, notice that they say there there are no "OS-loaded binary blobs" not
that there are no binary blobs at all. This is often the case with hardware
peripherals like monitors too. Any device that has software running on it
either comes with that software, or has that software provided by the OS.
> If so, what are the merits of the modem?
I don't know enough about what kinds of modems are available, so I don't know
if this one is anything special or not. It should work with Trisquel.
> Can I call with this X200 and Trisquel if I install the modem?
I think the way it would normally be used is to use cell towers for Internet
access on a laptop, not necessarily to make calls. It should be possible to
make calls though, with the right software. I'm not sure what that would be
though. There is a package called "modem-manager-gui" that might be useful.
Note that if you use one of these modems, it will allow your cell carrier to
track you just like a cell phone modem.
