Hmm, a quick google search gave me this link:

A fascinating (if rather expensive) tablet. Seems to match the given specifications...

Well, nearly match. Only one USB and only 1024x600. But the price tag - ouch! Not so interesting any more.

I guess that has a very good reason, "modern" devices are simply to flat to have any mounting points.
I find this an odd development: We're trying very hard to make our UIs more and more 3D, up to the point of sacrificing usability. And at the same time we're trying also very hard to make the devices using these UIs more and more 2D, also up to the point of sacrificing usability. I'd imagine it would save us a lot of trouble if we stopped both of these attempts.

I guess that might be true if you use absolute pointer positioning, like you typically would on a touch screen. However, if you use relative pointer positioning like on a laptop's trackpad I don't see why the inaccuracy of a capacitive screen should be a problem.
Think of the N900's/Jolla's touch screen as a transparent trackpad, that just happens to have the screen underneath it!
It would even give potential for increasing the pointer accuracy (at the slight expense of speed and intuitivity), regardless of the screen technology.

Might come in handy sometimes, though not necessarily when talking about smartphone features.

Capacitive screens tend(ed?) to have a lower "input resolution" than resistive screens.
Theoretically with the stylus I can control my N900 at pixel accuracy. Practically I get something between 3 and 5 pixels due to my shaky hand and not enough diligence during calibration.

Quick reply...

Hey... That's an excellent idea... Though a village on the Moon is more realistic...

Question: would GPS positioning work in space? That's a two-fold question: will the hardware be able to hear the signals over such a distance (Earth-to-Moon or Earth-to-Mars), and will the software be able to process it properly (or was it programmed for on-Earth positioning?).

[/Edit]

Related question: which navigation software would be able to use this GPS position for on-Moon or on-Mars navigation - show you the maps, and such?

Oh, and do not forget the Moon dust! It's worse than sand. So, you need a very good dust tight case for N900 ;-)

And Mars is hot, I expect. Sooo... Space-preparedness is an interesting topic. A challenging one :-)

Best wishes. Thank you.

It's either their way or you can bugger off. For decades reliable systems have been built on the idea that components should be loosely coupled together (this is part of what Unix philosophy is all about). This idea still runs true today, just look at Amazon's recommendations for building a cloud infrastructure or look at how the architecture of a modern web browser has changed to become more secure and reliable. systemd throws this idea out of the window. They currently plan to make systemd a hard dependency on udev and I just cannot agree with that stance.
A respectable viewpoint. I appreciate the honest and straightforward answer. Thank you.

It faded away because manufacturers decided you MUST replace the screen of your shi(n/t)y "smart"phone at least once during its lifecycle (upto 2 years, not more).

Could you replace ConnMan with a different network manager on a Jolla? Sorry if it sounds like a stupid question, but I don't know if there's alternatives for ARM devices.

Yes and no.
GPS (and other GNSS systems) in principle work in space. LEOs (low earth orbit satellites) even use it for their own positioning.
The antennas of the GNSS satellites however are always pointed towards earth. So you still get signals even above the satellite orbit's, but only from the satellites on the other side of earth that are not blocked by earth itself. No idea how useful that is though.
I'm not sure if it will still work close to or on the moon but I'd think so (certainly not on its backside) but due to the distance you'd have to accept reduced accuracy.
You'll need professional receivers for this though, not consumer hardware like you'll find in smartphones or navis.

Earth-based GNSS won't work on or close to mars, regardless of its relative position to earth.
I've read about similar approaches by using different mars-orbiting satellites for rovers. But the accuracy won't be near anything you'd expect from GNSS as these satellites aren't made for it and there are by far not enough satellites up there for a complete system.

"Hot" as in high temperature? No. It rarely exceeds 273K.

Much of the opposite, actually. It's further from the sun than Earth.

We've drifted OT here, but the Curiosity rover [1] used a relatively low powered CPU [2] (compared to the n900/Jolla), the major concern being whether or not it could deal with the high levels of radiation out there
