1. No... No it's not. You're completely wrong. On Google, one tap and I can reroute based on traffic conditions. I don't get routed to make illegal U-Turns and the route is based on live road information. Search results are completely accurate, based even on partial strings of business names, business types, names, phone numbers. If you miss the letter "s" on a business name in Apple maps, you'll get some weird business hundreds of miles away. I searched for McDonalds without the apostrophe and it showed me some weird Irish bar thousands of miles away.
Stop fabricating facts just to suit your argument. I work in development and we use the latest SDK and the rule of thumb is, if they pay enough, use Google because it's 100% better.
2. What?
3. That's out of necessity and convenience. Everyone has an iPhone and FaceTime is built into them, so don't tell me that people do this because they've used Skype and other video services and found them to be inferior. FaceTime has major issues with low bandwidth video quality allocation. If your connection slows down, it basically just shuts video down and there's a small window of opportunity to get a "low quality" video, but its video-to-image-frame rendering is poor. (Slow connection? Keep audio, take incremented screenshots and send those while the connection issues pass) Skype isn't MUCH better, but let's not act like cross platform is something you wave in front of peoples' faces and go "You should buy an iPhone! HMPH sucks to be you!" Having cross platform support is better for EVERYONE.
Every major company I've worked with uses Skype, Google Hangouts and even WeChat for video conferences because A) They're better, B) They're cross platform and C) They're consistent. If FaceTime is so great, go ahead and four way call your boss, your PM and your overseas supplier. Right now, do it.
4. Millions own iPhones. Integrating streaming enabled by default is a spam way of bothering your users. iPhones have the best audio engines in the industry, literally miles ahead of every other hardware manufacturer on the planet, and they waste it with this atrocious Music application, no equalizer settings, no way to set it to local only so you're never bothered about streaming and iTunes integration is horrid. Why does it have to recreate your library from local files? And the filing system? Don't even get me started. Individual folders for each track is a nightmare. But I'll give you this: listening to music on iOS devices is #1 in the industry, there's no exceptions. Listening to music on an Android device made me want to never listen to music again. But it could clearly be better.
5. Siri is "acceptable". But make no mistake: Cortana is better. So is Google Now. Siri is a gimmick and don't tell me it isn't. They spend all this time giving Siri the ability to answer such stupid questions as part of a running gag. Oh let's give her some Back to the Future jokes so people can post it on Facebook and Instagram. Navigation commands are super hit or miss, Google Now fires off not only specifically correct directions but even pulls the business or contact name. You can even navigate to a contact, saved location or "nearest *business name*". You can ask for song lyrics, set calendar reminders for specific times for specific things.

Again, Siri is "good enough to get basics down", but let's not act like it's as industry leading as the devices it's installed on. Apple Maps and Siri get their usage because they have millions of users cooked with the applications by default. But Google Now, Google Maps and Cortana are ages ahead and the gap gets worse every release. Google isn't sitting around thinking of clever ways to make pop culture references.
