Compare how little RAM Sailfish uses with Android, how little battery drain, etc. Sailfish has many advantages over other Mobile OS.



I also think that Jolla needs to release Jolla 2 smartphone in 2015 to attract new Sailfish users. But not everybody needs/wants to upgrade every year. For example, my Nokia N9 from 11/2011 still works very well, including its battery, multitasking, etc. I also expect to use my Jolla smartphone for some (2-4) years.
This is getting offtopic so it'll be my last post on the matter, but:

- Benchmarks can be deceptive. Sailfish may have some theoretical performance advantages, but in practice I don't think they're really there yet, and it wants better hardware. I have a Nexus 4 (bought primarily to try Sailfish on). On stock Android, and certainly on CyanogenMod there is just nothing like the level of stutter and frame drops that there are on the Jolla, and few if any performance related hangs. It's a much smoother experience. Also, bear in mind you're comparing a now 2 year old phone which operates at 1.8x the Jolla's native resolution, with an OS that has a higher baseline of resource consumption than Sailfish and with a SoC that provides similar benchmark results on Android. Also, the Nexus 4 was £135 when I got one 3 months ago, before it was discontinued ... Jolla even with the €100 discount is ~£205. If anything your benchmark results paint a dull picture for Sailfish and make an argument for better hardware.

Sailfish with 1.1 is starting to eat more RAM. Also, given the poor situation with Sailfish apps, Dalvik is a reality that most users will contend with. This ups RAM requirements significantly. Moreover, 2-3GB of LPDDR3 or even LPDDR4 (LPDDR2 in Jolla) is not expensive or difficult to put in a mobile device.

Battery drain is gigantic on the Jolla in a number of apps and usage scenarios. I think any advantage you cite is again theoretical. For example, the Browser (a car crash in itself) is way more power hungry under normal conditions than Firefox is in Dalvik on the Jolla. It's also slower, suffers constant freezes and hangs and even takes longer to open. Albeit I haven't tried it with the 1.1 improvements, so perhaps it's a little better now.

Unfortunately my N9s (I had 2) have not fared so well. I wanted to move back to one when 1.0.7 completely wrecked any semblance of useful connectivity on the Jolla for me, whilst I was on holiday. Fortunately, 1.0.8 was released the morning after I got back, and gave me a useable device again. I say fortunately, as the USB/charging port on one N9 no longer works without a huge amount of coaxing, and the other one won't boot at all (it had only been used for about 3 months). Both were manufactured by the Chinese OEM, rather than the minority which were manufactured in Nokia factories.
