I don't really have an opinion on nVidia, as I haven't dealt with any of their products for over a decade; my own problem with this is somewhat more abstract: I'm not a big fan of this constant drive towards merging all these tech companies (or indeed, any company really). Perhaps there are some short-term advantages for the ARM platform, but on the long term it means a few small tech companies will have all the power, which doesn't strike me as a good thing.
