I'd like to quell some misconceptions.
The sole purpose of the Ubuntu Edge Indiegogo campaign was to gauge interest levels at that very early stage of Ubuntu Touch's life. $12.8 million is certainly nothing to be scoffed at.
"Ubuntu Touch hasn't been nearly as successful [as Firefox OS in gaining OEM partners]". It has been confirmed time and again by Canonical employees that Ubuntu Touch has very strong support from OEMs. The delay is being caused by Canonical themselves because they want initial Ubuntu Touch impressions to be as close to flawless as possible. They have openly stated time and again that the first devices by Meizu and bq will be enthusiast devices, built primarily for developers and tech savvy people in order to build up the platform before they start mass production.
As far as apps are concerned, Ubuntu Touch is the first platform that properly respects web apps, Out of the box Ubuntu Touch will have more apps than both Android and iOS. Still native apps are always nicer than web apps and they're giving developers the time they need to build those native apps.
