Their email is better than any other in terms of reliability and features, their calendar integration, auto creating calendar entries for your upcoming trips
Very subjective and I’d have to wholeheartedly disagree. Gmail is simpler with a slick interface and decent integration with calendar and some of their other apps, however, Outlook and Outlook.com (web interface) has loads more features and options for a much richer (and more complex) email experience. The calendar and contacts (including tasks and reminders) are a fully integrated part of the app, so no need for other apps to be installed. It has a much better “learning curve” and synergy with other MS apps, ie. OneDrive, Office, OneNote etc.
I guess if your using a Chrome book/Chrome OS or Android, then Gmail may well be the mail client of choice, but for Users of Windows proper Outlook is miles ahead. Not sure about IOS... the Outlook App works very well and has a lot of features, can’t compare it to the gmail app on an iPhone or iPad though.
Each to their own though. Just can't see why they're cunts.
Because they are notorious for mining your data, deleting content, sharing data (via cookies, google analytics etc.) with other organisations (eBay for one) and a whole bunch of other stuff behind the scenes that the everyday user has no idea about.
