To Nokia Lumia 925 from Nexus 4
Maybe you could lead in the right direction on the following.
I have a Nexus 4 and -you could say- a rely heavily on Google services (Gmail, Google Cal, Drive, etc.). I really like Stock Android, but love the minimalistic design of the Windows phone. I find also what is coming with WP 8.1 very good.
Coming from Android, is it really that difficult to use Google services (like the ones mentioned above) on a Nokia Lumia 925?
