I work with stock market data daily (providing charts and technical alerting to end users) and the kind of growth Apple is having is just not sustainable, I mean it's gone from $320 last Jan to $532 today! I am a fan of Apple products, but I just dont see it as a good investment, I would suspect that it will either level off or have to talk a fall soon. So my personal preference is do not buy Apple, I wouldn't (even if I could stomach $525 per share!)
