Looks like the X3 is the last in the line of powerful Windows powered mobiles. Is it worth buying the device when iOS and Android devices have more to offer?
Okay, to address the first claim - there's no evidence that the Elite x3 is 'the last in the line of powerful Windows powered mobiles." In fact, there's evidence that there will be future releases, specifically from Microsoft. It's the most powerful right now, so it'd be a good one to buy. Microsoft has insisted it's committed to supporting
Also, as far as 'more to offer' out of Android and iOS, that's obviously a claim of use. I'm a long time Android user who switched when the Lumia 950 was released, and I haven't been able to switch away, despite trying phones like the iPhone 7, Galaxy S7 Edge, and OnePlus 3. To me, I can't figure out why you'd use an iOS or Android device when Windows Phone has so much to offer. I love Continuum and the Microsoft camera app. I think the Windows UI is definitely the best, and remembering back to the early Windows Phones, it does save me time to look down and immediately see the information I need so I can put my phone away. It's something that drives me nuts about the other mobile OSs.
But, I also subscribe to Office 365. I have my TB of OneDrive space that I use to back up my photos (even on Android) and it's also where I store and edit my documents. I have the Lapdock, a Huawei travel dock, and the HP desk dock, too. And I think snapchat is lame.
But yeah, Microsoft doesn't offer less - it's just offering something different, which you'll find users here appreciate and openly advocate for. It's not without its challenges, but it's a good, growing system that is supported by one of the biggest companies in the world, and they say it's here to stay.
Edit: silly hyperlink to video tool. Totally interrupts the post. I fixed it, but where it says, "remembering back to the early Windows Phone," imagine this video hyperlinked:
