I second the thought of buying one of the big game makers. Atari would be funny, somehow.
I also second the TV tuner suggestion in the post above mine... *sigh* Apple's all about media, but a TV tuner's a no-go?
Apple's printers... Well: They went out of the printer business at the right time - maybe even a bit too late. Printers are dirt cheap nowadays and the business only makes sense if you also control the cartridge business. And I don't see Apple creating 'yet-another-cartridge' or people actually _buying_ an Apple printer that only takes Apple cartridges.
Apple _should_ think about mobile phones more. iSync wasn't the great thing. They're always a step behind. Newest mobile phones? Not supported. People here switch mobile phones on a yearly basis, because with a new contract, they get a new phone. Now: That new phone is probably only supported by iSync in the last three months before people get rid of them again in order to get a new one.
Now if iSync were kept more up to date (work with those guys, Apple! SonyEricsson, Motorola, palmOne, Nokia...) or if Apple would finally make up its mind and create _the_ mobile phone (iPhone, whatever...) to end the mobile phone wars...
They could buy Nokia, for example.
