Well the fact that they been around for a "while" is proof enough, that their technology patents are BS.
I know a lot of fan companies who stick and try to patent pwm technolgy, and guess what their stuff says patent pending!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
But when it is "apple" none of those says patent pending, all of a sudden they patent them. Widgets were around for a while, and most of above, steve job is gone. Oh I created the first smart phone no other person should do it."oh I created the macbook air~!" Someone using a ultra thin book is infringing on my copyright, I hope this nonsense ended with Steve Jobs and his temper.
To be honest I could not stand him... yup other companies are just going to sit there, and ot create smart phones, you are going to bitch and moan about it.
