How are apple devices any easier to use?
As you say, it may largely be because of familiarity.
However, my experience with my LG smartphone- admittedly, barely had it for a month...because its LG's latest and greatest- has been an exercise in frustration, and not because of familiarity.
1) Several of the functions I've tried on both my LG and my Apple products have required an extra step. That doesn't seem like much, but it gets annoying over time. It also takes more time in aggregate. Its annoyingly inefficient.
On the Apple mobile devices, all of your apps are on the desktop. However, you can jump directly from any app into one of your frequently used ones with a double-tap of the Home button and tapping the other app's icon. Can you do that on any of the non-Apples? (I honestly don't know; I'm asking a genuine question.) There are also a couple of "pinch" and "sweep" maneuvers that let you do similar tricks on the iPads even more quickly.
2) When I don't use my iPod Touch or iPad for surfing the net for a while, all the browser windows I had open when I left are still there later. So far, my LG has shut all of my browser windows on me 3 times, bringing me back up to a single Google window when I open my browser.
3) I have yet to have a problem typing a response on my Apple product on any of the online forums I visit with just its stock apps. However, on ENWorld, the LG occasionally and randomly moves my cursor between my placing it and my starting to type on my virtual keypad. This makes visiting ENWorld on my LG an absolute chore.
On Ultimate Guitar's forums, the LG has a different trick. When I orient my LG on its side- as I often do because of my fat fingers- it orients the top of the thread response window outside of the visible screen. When I manually reset the screen so I can see the window, it jumps back to its original position. IOW, I can't see what I'm typing at all. I have to trust in my skills as a touch typist...which I really can't on a virtual keyboard. I actually took it to Verizon to make sure I wasn't doing something wrong. It did exactly the same for their techs. Their response- "Don't type in the sideways orientation." (Helpful, right?) No such issue with the Apple products.
4) took some pictures & movies of Edgefest and of my Mom's dogs. According to my LG, the pictures were too big to send via gmail, end of story. If there is a way to share it, I can't find it. In contrast, in the same situation (movie too big to send) my iPad2 asks me if I want to send an edited version of the movie, and lets me choose which section (and how much) I want to send. And then I can go back and take
another section and send
it. This is in its stock photo app. This means that it's dead simple for me to share big movies with my Apples, and so far, impossible with the LG.
I've had other problems as well, such as the LG becoming painfully hot to touch and telling me to unplug it while recharging on a (universal) car charger (from Verizon) with which it had worked just fine several times before, and did not recharge. I unplugged it and tried it on its home charger...where it went from 45% charged to 12%. I rechecked its connections- nothing was loose- and tried again, and it recharged properly. Nothing like that has ever happened to me with my mobile Apple devices.
Those were the ones that bugged me the most. How much of it is attributable to malfunction as opposed to it just doing things the way it is designed to do things I cannot say.
