And that is the reason i would like more cross-platform options. Forexample on iPhone i use gmail, google search, and other google apps if available. But seems like every major vendor wants a lock in. Google has its own services, apple has its own, MS now is creating their eco system. There is very less cross-platform support and IMO that sucks.
I go for cross platform options when I can.
But of the cross platform options out there lets face it Google is the best and I will say least restrictive. Apple is on the other end of the spectrum and by far the most restrictive.
Google services work great on everyone but iOS and that is mostly Apple's doing for the problems there. Google voice works cross platform just fine. Google email and contact syncing works great cross platform. They do not have these insane lock in like Apple does.
MS yeah that one is a bit more lock in but for the most part they are not to bad. Apple well in that department Apple sucks.
