so... how many companies use android.... for anything? At all? the fact that it is on lots of devices means nothing. Companies will either use windows, solaris, or maybe linux. at least the ones I have worked for.
China I think wants to move away from windows... and if you have tablets, sure, they often will have android. otherwise....
Android could probably be a replacement for all those scanner guns running ancient versions of Windows Mobile (most common place to still see them is probably Target, but they were also used in warehouses), unless someone's still making new ones.
