Yesterday we started to see some announcements of companies backing Enlightenment Foundation Libraries development. Of course, INdT was pioneer in that since it was decided to use it for Canola2. Later on I created my own company and we officially support EFL as GUI alternative (together with Clutter, GTK and Qt), being the first company to do that.
While there are speculations about which company is it, what I can assure you is that this company is serious and is not alone. ProFUSION itself worked on EFL on behalf of various clients and you may expect another press release about a big French internet and telecom company deploying a massive number of units with EFL pre-installed. Not accounting various community driven projects that choose it and E17 as its base platform, such as OpenMoko and OpenInkpot.
Bottom line? While EFL does not get the same amount of marketing and visibility as Qt and GTK counterparts, it is playing fine enough to be considered to ship in dozen million devices in the next year. Why don’t you consider it for your project? Be open minded and try it out
