LOL you first download chrome, Dude In my experience of Mozilla and Chrome. Chrome is a memory hogger even if you have 1 tab open it eats the memory and drains the battery read about it its all over the internet. While mozilla can't handle lot of multiple windows and tabs. The only browser i have seen which is rock solid and power efficient is Safari. Also the mail app won't be having much advanced features like other mail apps but it certainly does the Job for people who don't want advanced apps. And i use Fantastical over the calendar app but only because of the UI and AI but also the calendar app on apple is decent and it used to do the job for me before i moved to third party app. Also if you use Pages it is way too much better than Google Docs and Microsoft Word. I don't understand what you like in Google Docs any ways i feel Microsoft Word is much better than Google docs. I used to be a Windows Power user from past 20 years and from last 2 years i have been using Mac and it is amazing. Try to use the Mac apps again i don't know what they used to make in 2009 but certainly they have improved the quality of apps in mac in 2014
