I suggest caution about making the project look
too professional (and using an "implausibly" attractive female -- unless she looks understatedly geeky -- in even the most tame fashion screams "professional" -- "
cheap professional"). From what I can see, the Pyra "has a story to tell" -- a well edited story. While it would likely be unwise to open with such exposition, it should not be undermined with marketing that is too smooth (think of those awful corporate websites, and university prospectuses, with multitudes of anonymous, smiling people of a studied mix of skin-colours -- they are ubiquitous and sophisticated consumers [our target audience, I would think] get turned off by them, I think).
The Pyra's story has a number of strengths: made in Germany (sturdy, quality product, made by people being paid a decent wage -- "oh, the price is not so bad"), made by a small team of enthusiasts ("I should support these people", underdog status, "not just another gadget released and abandoned"), and designed with GNU/Linux in mind (this
is a niche market, but there are many thousands of people -- at least! -- that really do care about this thing and who are not well served in the market; especially that such an interesting device -- rather than just a laptop -- is designed for GNU/Linux should be rather exciting for these people).
So, if there is a female "user" model, perhaps it should be ED's wife, rather than someone with no connection to the project. It is a shame that the prototype is too late for FOSDEM (I found out about the Pyra from a video from FOSDEM 2014), but a conference video about the Pyra, with a prototype, that is then linked to from Slashdot, Hacker News, Phoronix etc. should spread the message well for an audience that I think would be ideal. All the videos that ED has produced about the production process -- which are interesting in themselves -- should be embedded in the pre-order/advertising page: they show that a) this is not vapourware or a scam, b) that this is both small scale and professional-looking (the Global Components pre-production run video) and c) that the producers really care about their product.
Oh, and though I know little about UAVs, a video of a drone being controlled using the DPAD and other controls of a Pyra would be really cool.
