To anyone who is actually taking this guy seriously, allow me to point out some of the Android issues over the years. Let's do the nitpicking for ourselves too!
1. The back button is broken. It has NO consistency and it's up to the developers who always screw it up. At least you know on WP you can press the back button to the last activity. On Android, some apps close out entirely, or you go back to another app without first going to the home screen. The back button on Android is sometimes like the "button to some activity that you were using some time in the past". No joke.
2. The UI inconsistency. Android's icons aren't all the same size. It annoys me so much how the some icons (like the camera, etc) are smaller than others and it gives the display a very untidy feel. At least all the tiles are consistently sized.
3. List scrolling doesn't remember scroll location. This gives me so much love for WP, I can't even explain. Basically, say you're scrolling a list of apps on the Play Store. You open an app's page, to look through it. You don't like it. You press the back button. The list comes back but instead of being at the location where you tapped, the list it at the very beginning forcing you to scroll all the way down AGAIN. It bugged me to no end. I have never seen this happen on WP, it always remembers list location, and it's just comfortable to use.
4. Google claims to back up your contact pictures along with contacts. But if you do a factory reset or sync your contacts to another device, the pictures that sync are at a pathetically small 100x100 pixel size or something, and opening the picture makes the person unrecognizable. Only if you open the contact and then open the pic does it sync the full-res picture (and sometimes not even then, it didn't work on KitKat for me -_-)
I could go on, but you get the picture, right? This guy is slamming WP for the smallest issues, without giving a thought to the niggles in Android that make the experience annoying. Pathetic.
