You can pick one part of my answer and isolate it from the rest if you like, but I made it clear: we have varying problems with what they do as a company, but many of us admire their larger impact. If you think controlling slide to unlock compares to popularizing the personal computer and the touch-screen smartphone, I guess we're just not going to agree. But I'm 99% sure we both agree that their patent litigation is ridiculous.
I used to admire Apple back in the day, not any more. For example, 2011 MBP laptops are having huge problems with the GPU and Apple is saying nothing. The user forums at Apple are overloaded with complaints, but no employee dignifies that with an answer. To me that seems like very bad customer service.
I can't speak for what the grandparent commenter meant by his problems with the company, but I think that was one of their 'biggest contributions' and needed to be mentioned.
An iPhone developer and a founder of a company passionately argued with me once saying "what if they have found out the 'perfect radius' for their corners where their phone looks the best (say 5.6 mm), which no one else could find before? It definitely deserves to be patented".
I was facepalm. Many people just don't think it's a problem, and don't realize how it is ultimately bad for them and their children.
Like promoting useless patent litigations of 'rounded corners', 'slide to unlock' nature?
