I can understand this to a degree. I switched about 6 months ago from a windows machine to a Mac and dumped my (broken) Lumia for a second hand iPhone 4S. I went from exchange to dovecot IMAP for email with no calendar or contact implementation all hosted by me on a Linux box on Linode. I used Mail, iCalendar and address book. About 2 weeks after setting that up I got pissed off with it as managing contacts and calendars was messy to say the least so I did some research and for a CalDAV and CardDAV server together. This never worked properly and was a bastard to integrate and manage. So I said screw all this shit, moved it all to Google Apps laboriously and bought a Moto G phone. Now someone sends me an ICS file, I can't add it to my calendar as nothing opens ICS files on the device, I keep losing contacts and everything wants my contact list. Not only that, every attachment I was sent means I had to upload the thing to Google docs and convert it before I could open it in sheets/docs. So here I sit this evening with my broken Lumia 820 and a Torx T4 replacing the screen and a fresh Office 365 account. That was the last thing that works properly for me. I imagine they'v gone through the same hell. Whilst I understand that not all workflows are like that and this is an anecdote, I appreciate what compatibity does for people and why ecosystems are persistent.
