Jobs was a visionary and American iCon. Those claiming to hate his company's products probably possess a knockoff of one his company's products.
I have a long and painful history with Apple products, from the Apple II all the way to the Macbook and iPhones and iPads. I have found them no better quality-wise than any of their competitors, with the caveat that you get what you pay for, so if you buy cheap discount computers you are going to get cheap discount performance and service. But with Apple you pay premium prices and get ok products with ****TY service.
Our Apple II died after 6 months. It could not be revived and we moved on to IBM. My wife's Macbook could not run basic software that she needed without crashing, then the motherboard died (RAM interface went bad), we switched to HP and that laptop has lasted years with zero issues. My wife's iPhone 4 has been returned to Apple 3 times now because of the faulty headphone sensor that causes the phone to route all sound to the headphones whether there are headphones in the jack or not (a known issue with the iPhone 4). They still haven't gotten it right and they won't replace the phone either, so we either buy a new one or live with it. They also tried to charge us for the 3rd repair job. My son's iPad 2 locked up when streaming content from the internet. It has been returned more than once to repair since a reset and update of firmware did not fix it. It still locks up occasionally and no one knows why (another known issue we are told, but less common than the iPhone problem). Again Apple's wonderful return policies are such that they won't replace it. They are anything but perfect products the way the Apple zealots would have you believe. No doubt they have done a lot to push the envelope and cause others to advance their tech as well to keep up, but as a product set they are pretty much average quality and as a company they pretty much suck.
Don't even get me started on the 2 times iTunes has wiped out my wife's music catalog that she bought from other internet sources (mostly amazon) that just disappeared the first time iTunes raped her computer pulling in and ****ing with all the media.
Sorry, didn't mean to get off-topic when this should be about Jobs and his contributions. Just that Apple is not as impressive to me as it might be to others, and the loss of money and time and hair due to frustration is enough to make it a trigger-point for me.
