Hi.
I would like to add the following:
.- I hadn't seen any real innovation on mobile devices since 2011. More CPU and more Ghz usually mean higher prices to run the same software. For instance: parallax was something available in the N900 long before it was announced for the iPhone 5 ... four years later.
.- I still can't believe that with so much processing power, Android is not doing multitasking.
.- I don't expect real innovation in the foreseable future, and this means the N9 will get obsolete much more slowly..
.- I might seem paranoid, but I don't trust hardware from companies outside the EU in terms of privacy.
... and this leaves Harmattan, Maemo and SailfishOS as my only alternatives.
For me Maemo is much more friendly, Harmattan is an unfinished product (yesterday I flashed my main phone for 2nd time in 9 months) and the aegis stuff is sort of a PITA. And SFOS is still very expensive for me.
I also don't expect much from other initiatives like FirefoxOS or Ubuntu phone ... or even Tizen, but we'll see what happens in the next years..
Regards.
