Investment in the mac
I realise that Apple is moving away from the Mac and it's a pity.
I'd like to see them investing some of their pile of riches into greatly expanding their mac user base.
They could reduce the cost of the MacPros and make them seriously competitive in price with standard high-end PCs.
They could buy EA and have all their games released first for the mac. They could produce a serious games-oriented Mac.
They could buy Ireland.
They could strive so that from, say, 2014 on, everybody's first computer would be a Mac. The iPad should point the way to get Mac Minis into every bedroom and livingroom. Make it $300 and offer MS Office for almost nothing. Offer greatly subsidised MacBooks to students and schoolkids.
In other words, make them an offer they can't refuse.
Maybe it will cost $20-30 billion, but if it also ups Apple's marketshare of computers (rather than tablets, smartphones and the like) used to 20-30%, it will have been money well spent. Of course, Apple won't be able to keep this up for too long, but the hope would be that the seeds once planted, will take root and remain.
Alas all of this runs contrary to Apple's modus operandi, but it doesn't sensible to me.
