I think there are going to be waves or generations of Android software. We are about at the end of the "porting wave" and we'll next have a wave of apps that really digs in to the modularity, IPC, background processing, and RPC technologies available in Android. Facebook was an ambitious first try at a suite of cooperating apps, and I expect more successful attempts to follow.
In my anecdotal experience, for example, more college students try to do Android development, since they already know Java (taught in most college CS classes), whereas the students that try iOS development only do so because of the cachet of having an iPhone app.

Speaking of Android phones, see for example the Huawei Ascend p6, not yet Samsung Galaxy S4 territory but it's getting closer:

Edit: for completeness, a ZTE high-end phone, not yet as polished as Huawei's I think. Sold as "Sprint Vital" in the U.S.
Amazon, OTOH, does have paid app purchases, and so does Baidu.

It seems Google is going to offer paid apps soon:

However language probably is a factor...
