Compared to desktop operating systems Android does very limited multitasking or, to put it in another way, it is cleverer about multitasking (iOS, too). Remaining backwards compatible while picking up such a new model of multitasking is hard. Very hard. Apple made parts of it opt-in with Lion but that’s not the same as requiring everyone to adhere to the model and today hardly any app supports it. Gruber simply sees this as a hard challenge that is, at least currently, not solvable if Windows is to stay backwards compatible. That’s all. He might be wrong but I think that position is quite sensible.
