1. Size: that thing looks absolutely tiny. I don't think a 3d printer counts as viable when the largest thing you can print is a espresso cup or a shower hook. Maybe some people are in the market for this, but not me.
2. Weight: Saying you make it light is okay, but i'd be concerned that it may be light enough to wobble itself around your desk.
3. We build our own software for you!: I'm skeptical. Looks like we are going to get proprietary slicing software to attempt to lock users into the brand. Not horrible, just disappointing. An awesome open source slicing program seems better than 5 dozen mediocre proprietary ones.
All in all, good on these guys for getting out there and making something cool. I really don't want to be a negative nancy, because they are out there actually building things when others just talk a lot, but i'll wait and see it first.
