No problem mate, thanks for the reply! I mostly agree with the touch latency, even with Nexus 4 it's not as good as iPhone. But it's getting better. API issue

No problem mate, thanks for the reply! I mostly agree with the touch latency, even with Nexus 4 it's not as good as iPhone. But it's getting better. API issues: there are different API versions that are backwards compatible. But apart from that, the API is the same across devices. Manufacturers don't change the API. Having to use older API versions can be a bit annoying, but I don't see it as a big problem, and there's also the support library.
