So I returned to iOS with the iPhone 6s recently (just under two weeks ago) from BB10, which I've been using for the past few years. I love the 6s's design. It's beautiful in the honey-brown leather oem case I bought. Understated, modern, but feels like a well-worn friend already (the case, not the screen). The darker camera module on the back, and the blue front camera module on the front is really beautiful compared to the iPhone 6. Little details make the device special. And of course the build quality is the best I've seen. But then it comes to operations, and I find myself lost. BB10 was very simple and clean. Multi-tasking is BB10's strongest quality, I think. And Apple's iOS just makes me confused by the way it handles multi-tasking. The 3D Card system on a double tap of the home button takes longer than just going to the home screen and finding the app you want again. It's almost only useful for closing a malfunctioning app. And yes, I've discovered the force-touch app switching (from the left side). The thing I miss most is the ability to be playing a YouTube video in the browser or in FastTube (my YouTube app that allows me to preload videos for later) and having the video continue playing if I want to check my email, check my calendar, or even just adjust my brightness. The other thing I miss is the ability to tell iOS where I want to open a link. I found an iOS YouTube app that allows me to switch the video to just audio so that it will play in the background, but I'm not able to open links directly into that app (in BB10, this is simple and easy to do). Very frustrating. Similarly, uploading photos to DropBox requires that I continuously reopen the app because it will enter a save state after a minute or so. Another small thing is the speakerphone. Not great on my 6s, but my Passport feels like a conference phone. The things I love about iOS are there too. iMessage and FaceTime are Apple's greatest assets, though I'd love it if they produced third party iMessage apps. The new NightShift feature is the one reason why I'm actually considering keeping the iPhone. It's become that important for me. I use F.lux on my Mac as well. Live Photos are really well implemented (not a new idea, but an okay idea done really well), I love these. And the fingerprint reader is instantaneous and amazing. There is a lot that I love about iOS and iPhone, and a lot of that is human relationship-centric. But the underlying operating system has major limitations and issues that lead to a really awkward user experience. People always talk about how simple iOS is, but it can get really convoluted the way you have to contort yourself around those limitations. To share a photo from OneDrive to WhatsApp, I had to first download it to my Photos app, then open Photos, find the photo I just downloaded, then shared it from there. Whereas in BB10, I can easily find the photo in my File Manager and share directly from that location. BB10 is simple but powerful. Maybe this is the best analogy I can give: you know how the Apple Watch is meant to be a satellite for the iPhone? Well the iPhone feels like a satellite for my MacBook Pro/Workstation PC. And well, my BlackBerry Passport feels like a satellite to nothing but my information/email accounts/cloud storage services, like a laptop alternative. ----- So this is probably the wrong crowd to be preaching to, but I've been an iOS user since the iPhone 2G. I've been a Mac user since Tiger (and I actually had an OS 9 computer as a kid). But there are a few things I feel iOS really needs to do better in the future. -File management is convoluted. A simple file manager won't complicate iOS, it will simplify it. -Second is a better window manager: the flat, WebOS-style card system was better than this weird Windows 7-style manager, but really, something more like Expose would be ideal. Expose is amazing on OS X, no reason why Apple can't come up with something that allows the user to see everything that is open even on a small screen...BB10 did it (though it also only allowed a limited number of apps to be open, and it offered true multi-tasking due to this) -Third, true multi-tasking. Why can't I bounce between apps at will in order to get things done more efficiently (all while I have a youtube or internet video playing in the background, or while files are transferring to dropbox, or copying between my internal storage and SD card)? Look up a BB10 videos, the ability to move between messages and apps is unbelievably simple and efficient. I'm aware of everything going on in BB10, whereas in iOS, everything is a little messy and obscured. Why not just add a window management page to the home screen? Or left of the home screen, or from the top of the home screen when you pull down (kind of like Spaces). There are so many ways to do it better. Anyway, thanks for reading.
