In the 1980's, Apple's technology was pretty bad. It's arguable if Microsofts was much better, but they hardly created any shovelware. Note also, that Apple's 1980s strategy of locking down devices, software, and hardware was a leading cause of their failure, even aside from their poor operating system offering. They almost went out of business, until the return of Jobs and the Next assets.

The same strategy may fail them again. I certainly would never have even looked at a mac laptop if it were as locked down as iOS is. Although people often argue that mobile products are different, I disagree. They are simply small form factor computers and you need look no farther than Android to see that an operating system as flexible as a desktop OS works just fine in this area.
