Dw guys. Third party apps are awesome on WP. Youtube=myTube, metrotube or tube cast. Google+ = gplus. Dropbox and google drive= one drive and cloud 6. Hangouts messaging = im+. Google now= cortana, Google maps = gmaps, bing maps or here maps, hangouts calling = Skype. If Google won't support us then we will support ourselves.
Better yet, just don't use Google services. The only reason I have a Google ID is for use of Youtube.. That way I can keep an eyes on what I watch on youtube.
I have no need for G+, Gdrive,Gmaps,Gdocs or any other G whatever.
I have a 3rd Party app on my 1020 for youtube but since Cyan Update I mostly now just watch in browser.
Yes switching over to only MS services can be a bit of time and hastle, but you can do everything you need in the MS ecosystem.
Here Maps and Here Transit I have found to be wonderful from day one, and I was shocked that my Towns Transit system was covered by Here.
Here was most useful when my trip covered Multi Bus/Multi System trips........Guelph Transit-> Go ->TTC
If your company requires G option then your stuck. However I can live without access to Google, and if I dumped my youtube, I would be free of Google complete.
