For that matter, what exactly are Jobs' accomplishments other than being able to market stuff to convince people (including, apparently, legions of hypersensitive nerds) that he invented / perfected it?
You can like the walled garden for legitimate reasons. You can like specific hardware for all sorts of legitimate reasons. But the iPhone 1 (for example) was such a massive pile of shit, but the marketing/fanboy RDF plus the fact that it came out pretty much right as Youtube and Facebook-for-the-masses were being launched made hundreds of millions of people sit up, take note, and associate the whole concept of of a smartphone with Apple and Apple alone. (Despite the fact that the damned thing wasn't even 3G, had a significantly worse app environment than Android, couldn't send pictures using the most widely supported standard of the day, MMS, etc.)
It's really one of Apple's worst products, but because of their incredibly fortuitous timing, their glitter (though sadly-delayed N900 was better, even with resistive touchscreen) , their marketing and their unusually loyal fanbase it became the most important and successful product line they ever make. I mean hell, pre-iPhone, most people I knew didn't even realize they could use their existing phones as MP3 players (e.g., the second generation RAZRs could), and with a far longer battery life than the iPhone could manage. Jobs deserves credit for being able to alter consumer's knowledge, perceptions and behavior, sure. But that's not how his accomplishments are typically described.
