I hardly think my MacBook Pro is a toy! It's a powerhouse that does nothing but pound out video after video and oh yeah, NEVER crashes.
No the MacBook Pro is not a toy. And given that the operating system can be designed around a motherboard that is fully defined to the developer, that the peripherals must all meet Apple's standards and that the software must pretty much all be Apple certified, it is not surprising that it rarely crashes. The iPad is primarily a toy for most users, however, and is outselling the industrial strength machines in the Apple fleet by orders of magnitude. Apple could lose their real computer business entirely and still be hugely profitable.
Until recently, Microsoft has not been a computer builder, but an operating system monopolist, and somewhat less successful application developer. Lately, Microsoft has been suffering from a probably terminal case of Apple-envy, and has responded by trying to copy what it sees as Apple advantages. So we have the developer of the de facto universal operating system, requiring driver certification for add ons, certification for software etc. These are things that will make life easier for MS but maybe harder for the host of hardware and software developers who have fed at the Windows trough so successfully. By entering into direct competition with these commensal entities via production of their own tablets, Microsoft has found another way to get a leg up on the competition.
In trying to integrate an operating system that will look good on a tablet, and host a multitude of silly (but profitable) little "apps," with a universal OS for serious computing, however, Microsoft is in danger of throwing out the baby with the bath. Clearly that is what most of the market wants. If Microsoft runs after this market and tries to out-Apple Apple, to the detriment of "serious" computing, it does not bode well for Windows based computing, or for the variety and innovation that a sort-of open OS has provided for the past few decades.
