Does no one else here see the parallels with 'Apple should just make OSX for PC and licence it or they are doomed' style nay saying?
Not really. Apple always made money selling computers. At the moment, they make tons of money selling computers (they are making more selling iPhones and iPads, but the last published estimate was that Apple takes 45% of all profits in the computer hardware market, and that was before Dell dropped and Acer started actually losing money). The console makers don't make money from consoles, but from games. Both iPhones and iPads massively outsell the console makers. The hardware is probably superior to any Nintendo handheld device. If it isn't, then next year's hardware will be. 70% of revenue is more than Nintendo will get from any game sold in a store.
All that Nintendo has to do is avoid trying to sell games at low prices.
