Get XWayland running, the 1 million android apps didn't write themselves, so potential market right there. Jolla (the phone) can pull this of. Wanna write your android apps on the go? Run Eclipse or whatever latest IDE on your mobile device. No other android/iOS device can do that (add to that geeks with gimp, even though screen...). Sailfish is a real computing platform, look at all the 'android studio for android' apps in google play store which have barebone features and only java and very limited in that regard. This with mass produced hwkbdOHs would be a differentiating factor (still not for tens of millions of users, but for developers, yeah)
