Based upon images dug up from the Ubuntu server it appears that Ubuntu Edge is a smartphone and what would be their first official smartphone product. Up to now Ubuntu Phone/Tablet testing has been done on randomly supported hardware like the Google Nexus devices that ship Android by default.
Also worth pointing out is that on 22 July, when the 4-day teaser countdown ends, marks the start of the OSCON conference in Portland.
It will be interesting to see the specs on the Ubuntu Edge and what Canonical has come up with and who they have partnered with for producing this phone. Canonical does have the Ubuntu Carrier Advisory Group, most of which are non-US based telcos so it will be interesting to see if for their premiere phone they are even launching in the US. I'm not anticipating the Edge will be competitive with the current Google Nexus or iPhone devices, but will likely be a low-end offering.
