1. No need to have a WP for MS services. In fact, apps for those services are apparently more up to date on other platforms.
2. Android is somewhat similar except I think once on the home screen, it doesn't do anything. Which is why the back button on XBone confuses people lol.
3. Agree with you here. The home screen on WP is the last bastion.
4. Yep, it performs well. So do iPhones and high end Android devices though.
5. A lot of this is changing. Especially since apps are just using designs from their implementations for other OSs. MS apps are probably getting updated to remove a lot of the nice flow of Metro such as Pivots and all. Swiping is a much nicer way of navigation than button pressing in my opinion.
6. Hardware is nice, but you don't need WP for that. Plus, we have yet to see a solely MS developed handset yet. At least I would imagine all of these that have been released since the purchase were already in progress.
1. That's not true across the board. No Cortana is a biggie (for me). The Exchange app they bought for Android and iOS is good, but it has a long way to go, and it doesn't have the contacts/calendar integration of the built in WP solution....yet. OneDrive is decent, but automatic camera uploads isn't as integrated, so it's a little more clumsy (I like that there isn't anything in the notification bar on WP, it just happens seamlessly in the background). Office is excellent on iPad, but integration from OneDrive (where I keep my files) is still a bit clumsy, though it is rapidly improving. No Office on Android phones that competes with the WP implementation. Skype has some added features on other platforms, although integration in WP is supposed to lead to better features on WP eventually, like integrated messaging. OneNote is really good on all platforms, but handwriting on Android and iOS would make that version better for a lot of people (I don't use it, though). What I've seen of W10 mobile should put it above the other platforms for most of these services, but then again, updates to the other platforms could bring feature parity by the time it launches. I think once Cortana is launched on the other platforms, it'll be a huge deal, but the fact that its not integrated may still tip the WP version as superior.
2. iOS needs a back button
4. iPhones have suffered from the same performance degradation as WP phones have with each new version. Android performance is all over the place, and highly dependent on device, specific apps that you use, etc. even on high end. I started with a super fast, smooth, amazing battery life high end Android flagship, then 8 months later it was a different story. Battery life was shot to hell, lag, glitches, and frustrating day-to-day issues like the phone not immediately waking from sleep when I press the power button. I know this can happen on other platforms, but it's almost an Android trademark, like the classic Windows rot that requires you to refresh your device from time to time.
5. If we're honest, many third party apps never bothered with Metro, and those that did ended up not updating their WP apps much because of the extra effort it required to maintain a visual style for one app while their iOS/Android apps looked pretty much the same. It's a problem on Android and iOS too, so I think there is nothing to be done, and MS is simply starting to adopt what is increasingly becoming industry standard UI and navigation. Sucks, but that's reality. I love me them hubs and pivots, but it is what it is.
6. While other manufacturers are stepping up their design/materials game (HTC and Samsung for sure, along with Sony), none other than Apple has created beautifully crafted phones with phenomenal cameras the way Nokia did. That could change this year for Android, but who knows. At least for me, that's the winning combination. Even Apple has gotten away with low MP sensors because of fantastic software, but if they step up their sensor game this year (16 or 20 MP), then damn, it'll be lights out until the 1030 arrives.
