Regarding the iOS apps and removing the stock ones, I read somewhere that you can't uninstall them, but you can hide them so they don't appear on the home screens.
I have a 950XL, and I love it, but I'm at the point that if someone offered to buy it, I'd probably sell it and my Continuum dock. I love Windows 10, but the apps on other platforms are just so much better. I got a BLU RD1 Android phone that I've been using today. Android is such a horrible interface, I can't find anything, and notifications confusing because they're all jumbled together. The simplicity of Windows 10 and how information is readily available on the Live Tiles just blows this thing out of the water. But I hate relying on third-party apps to control my Nest. I can't support most of the Kickstarter or Indiegogo projects that I think look cool because they require an Android or iPhone app to set up. None of the stores I shop at have a Windows app, but if I use the iPhone or Android apps, I can pay with my phone and get coupons. Amazon Prime Video? Not on my Windows phone. Periscope? Nope. Pinterest? Shall I create a board of unavailable apps? My wife just switched from a Lumia 830 Windows phone to a Samsung Galaxy S7 Active because of battery life and Pinterest. With the 830, she'd have to charge the phone before she left work. Now, with the S7 Active, when she goes to bed, it's only at 60%. My Lumia 950XL won't make it through a day without a charge, although admittedly, I have a lot of apps running in the background.
My frustration is mounting, especially when, being an enthusiast, I pre-ordered and paid full price, but keep seeing the price drop in other countries or seeing these buy-one, get-one specials. I was looking at my collection of Microsoft devices because I'm putting the others up for sale. Original black Zune, red 120GB Zune, Samsung Focus, HTC Titan (I), Lumia 920, and my old favorite, the Lumia 1020 with wireless charging cover and camera grip. That camera was just incredible. It feels like I'm breaking up with an long-time girlfriend; I love her and don't want to hurt her, but sometimes there's only so much you can put up with before it's time to cut the chains and move on. I sure wish Project Astoria hadn't been dropped.
