It is also at the low end that things get interesting. Most people get caught up in this fight over Android and iOS, so they never see that they are completely divergent platforms. Android will achieve ubiquity over the next few years. Toasters to phones to tablets to GPS units to military handhelds will all run it. The only thing that has been holding back such ubiquity so far has been Google's refusal to license the Market to devices which do not contain a "phone". If and when that changes, things will start to heat up. We already have decent $130 handsets running 2.2. How long do you think before Android is the new Symbian, with people buying "dumbphones" with Android without realising they've got it? Fragmentation be damned, it is a by-product of ubiquity.
