Bra kommentar angående diskussion om UI på lumia där man jämför lite med N9 (MeeGo Harmattan)

Citat:
Any UI/UX designer will tell you that the most important thing in a design is consistency. Blatantly put, things should always be at places where you expect them, whether they are used or not.
To make a parallel with desktop or web UIs – there are dialogs, forms and what not, which can have various options/states in dependence of what you have chosen in the earlier point of the app. By your suggestion, options that are currently unavailable or unusable should disappear from the UI (e.g. reset button on a form where you haven’t filled anything in; or a drop down to select a language if you’ve selected ‘Auto-language’ check box) – however, that adds up to inconsistent UIs where you cannot predict and/or immediately see the effects of your current action, and there is a plethora of research that says that user find that confusing, alienating and even uglier even if you present them with the same design and style, but just with missing options.
That’s why the multitasking screen is always there, whether you have running apps or not. That’s why so many people are awestruck by the Swipe UI – for probably the first time Nokia has created a really consistent UI and people instantly find it friendly, solid, beautiful, fun etc. If only they could’ve solved the back problem without an additional button, but without compromising the Swipe UI paradigm… Harmattan UI has only two big inconsistencies, the aforementioned `back` problem, and that it doesn’t provide an instant feedback (either through a generic loading splash screen, or at least an animated/bouncy/whatever icon) when launching an app from the icon grid. Given all, and considering the history, this is quite a feat for Nokia.
Also, on any proper multitasking system – and the N9 certainly falls into that category – there really is no need to close apps, provided there are enough resources to manage them and that the apps are properly coded. In fact, closing apps for no reason whatsoever is completely counterproductive as it will take more resources to relaunch them when needed, not to mention time and the user experience of it, then to keep them in memory at all time.
The RAM memory spends the exact (well, statistically negligible difference) amount of juice both when full and when empty so by cleaning it data used by the apps that you are not using at the moment doesn’t give you any battery life benefit – in fact, when you do need that app and while you are starting it it will take considerable resources to read it from the flash memory and to put into RAM the things it needs. It also doesn’t affect the performance one bit, nor does use additional resources if the app in question doesn’t have leaks and doesn’t do anything in the background and doesn’t utilize additional hardware (e.g. GPS, sensors etc.) – or more simply, if it’s properly coded, and I take that at least the basic apps are.
Of course, the above becomes invalid when you use up all the available RAM so the apps need to use swap space, but then again I’m not suggesting to leave games, maps and such apps always running. The N9 can multitask – use that to your advantage, even if it seems counter-intuitive to you.
