Probably the more significant thing is that it's a self-powered forced-air rocket stove (part of the current generated drives a fan). The self-powering is interesting, but I'm not sure how much it adds or if the forced air just makes up for the energy taken out by the electronics.
The rated output (2-4W @ 5V) seems impressive, but I'm not certain I buy it or at least I'd wonder just how much you need to be feeding the fire. I don't see any mention of a battery pack, but I think if I'm charging expensive and sensitive devices I'd rather charge batteries, then charge my devices with a more stable current. Adding your own battery is going to bump the already-considerable weight (> 2lbs).
They do present a comparison to the "conventional alternative" of an alcohol stove + fuel + solar, but for some reason it seems designed to make the conventional alternative as unappealing as possible (44 oz & > $200 for a stove plus fuel for 2.5hrs of burn time!). Not included are options such as a simpler rocket stove (easy to make) or a SuperCat alcohol stove (cheap & REALLY easy to make) and options to make those more efficient (shrouds, etc. sized for your cookware).
As for charging, there are actually some pretty impressive solar options designed for backpacking - they aren't on-demand like this, but many of them incorporate a battery system and could likely be used on a pack while hiking, so the battery pack is available when you stop, and you can use them in places where you don't really want a fire.
I'd have to call this fashionable, but I'm not sure how practical it really is for most people.
Edit: forgot to mention, the base unit for this is ~$130, and the kettle/carrying case adds another $50 and 1 lb to the whole thing.
