I just got my first MacBook so I'm still learning how everything works but the native apps are very nice. If you're familiar with iOS the interface kind of reminds me of that - there is a mail app that will fetch your Gmail, Safari, Calendar, Notes, Maps, Messages, FaceTime, iTunes, etc. With Pages (word documents), Numbers (spreadsheets), and Keynote (presentations) you can export to the corresponding MS Office file type. Everything backs up to iCloud just like in iOS. I downloaded Chrome (my preferred browser) since that has flash built in whereas Safari was asking me to download a plugin. I'm waiting to get Office for Mac 2014 when it comes out in the Spring.
