Looking forward to the Sailfish OS being available to install on Android devices. Sounds like it's based off of Nokia's Maemo OS; which was sorta Debian on a mobile device. You could even install packages with apt-get.
Sailfish OSI've had several androids in a row and now have the HTC One as well as a Nokia Lumia 920 running Windows mobile OS.
The Nokia is leagues ahead in hardware and is so much faster in the OS/app space that I find using the molasses-slow Android device a pain in comparison. Maybe when HTC pushes out the Kit-Kat update next month the Android device's performance will improve. (from what I understand, Kit-Kat is supposed to reduce resource req/improve speed, so it might even speed up older android devices).
But even beyond speed, there are bugs all over Android and Android apps. Tune-in, for example, is complete shite on Android--can't maintain a stream and crashes all the time. Whereas Tune-in on the WIndows phone works without any hiccups.
Android has a lot more app choices, but how many apps does anyone actually use? Not being twelve or a chick or gay homosexual, I've never seen the point of candy crush or other mobile games. For all I know, they might be available on Nokia's Windows devices.
Windows mobile OS has doubled in market share over the last year, at the expense of both Blackberry and even iOS.
Android's 81% market share (globally) likely will be balkanized next year by other linux for mobiles like Sailfish and Mozilla's upcoming Mozilla OS and then the flood gates will open and google's Android market share will crater. And that will be a very good thing. Java's painfully slow and buggy on the desktop. No idea who thought Java would be a good choice for underpowered mobile devices. Probably the same geniuses who gave us Google X, Google Wave and Google Buzz.
Firefox's OS apps are built in HTML/JS/CSS. Sailfish uses QML for app development. QML is built on QT, one of the contenders for the next gen linux desktop window-manager.
http://en.wikipedia.org/wiki/Razor-qtThe guys behind gPodder, a great podcatcher app and service, did a FLOSS Weekly recently and basically said they've no desire to port their app to java and android. (tho it might be deployable to android if you root your device and sideload). They have gPodder for mobile devices running in QML (Nokia's N9 Maemo device and Blackberry's new OS run QML apps) and they are sticking to improving their QML version and waiting for the market to come to them.
Beyond Android, the deals running this month on the Nokia 1020, Nokia 1520 phablet and maybe even the Nokia 2520 tablet are worth checking out. You might find that other than for hacking and developing, you'll never wanna touch another buggy, slow Android device again.
