  1. That is so sad that this is what it came too. I guess the best bet now is to work for the corporations if I want to see any of my technologies make it to market. I need to have a big company on my side.

  2. You are making me not like Apple that much anymore, I was thinking of applying for a senior position. But if this is true about Apple, I would not feel right working there, and besides I would rather stay in my country (:

  3. it is stuff like this that happens, a big company changes things around a little bit so little inventors get screwed. Apple why don’t you be fair to others?? I designed a new smartphone including designed updates that would support existing operating systems the ability to run this advanced device. But I am afraid to show anyone because of this kind of shi* that happens, Apple why do you do this to people that are only trying to help innovate?
