One of the things I love about Google Apps is the way it manages presence, and its funny that not many folks write about that. Presence, to me, means managing what I'm logged into and when online.
Perfect example... today I'm bouncing between the office and home. Have a Chromebook at each place so I don't have to carry. Google a) knows when I'm online, and where and b) perfectly manages having my documents, calendar, contacts and well, every other aspect of my online life readily available. This is freedom I never experienced with Apple or Microsoft (although Microsoft has certainly made inroads with their new Office release. Not bad, just not great).
I would say, the only area where I feel like Google was a little weak was in Photos, but I got all of mine uploaded before I gave up my last Mac. Its coming along. iPhoto was a category-defining product, a little less so today, and for the little bit of hobby photography i do (2500 photos), Photos is fine. If you're on the fence about Chrome and Google, I'd encourage you to give them a try. And you don't have to give up your Mac or Microsoft device - Google's apps are platform agnostic.
