So if you do not know what are modern apps and you do need UI with buttons, why did you buy jolla and not n900 that has most apps jolla has and cheaper and more hackable?
As well as it's kind of funny to hear guy who talks about open source and on other hand says that there is no need for several same apps. Maybe the freedom of choice and as well as competition is good.
You may as well tell that there is no need for Facebook or Twitter, but currently there is no proper apps even for that.
But again I feel that any app that most people are using (even if it's not important time-waste apps) and is not on jolla I mention you'll tell there is no need for that. But guess what, I want to decide not to use Facebook app/chat and not to be forced because there is no option. Those apps maybe are not most useful, and maybe you use ssh to connect to home server to switch song from toilet more often than using apps with UI, but those apps are standards for any smartphone.
And about UI vs console. Yes on computer console may be more useful than gui apps in a lot of cases, but not on the phone. You can't admire swipe, gestures and pulley menu (features of jolla being unlike) and at the same time to say you use console. You see the logic here? If you like swipes so much, but use only console apps?
And yes android and iPhone have hundreds of thousands shitty apps and programs, but still even if they have 10% of cool apps it's way more than jolla has in total - not to compare, just telling that you shouldn't judge android by bad apps, but by good apps, as most services, gadgets, iots support android out of box, android has system administration, console and terminal, and you can even compile kernel. So if you compare you should not compare good side of you fav product with bad side of other one. Btw there are roms which are more open source and hack friendly than jolla
