Apple didn't innovate anything. Why do people praise them?

After watching the WWDC I've noticed some stuff weren't really new innovative ideas. Parallax was taken from The Astonishing Tribe (TAT, owned by BlackBerry) and added to the UI, the swiping gestures were taken from BB10 OS, Air Drop is basically NFC, the App Store looks similar to BlackBerry World with a white background but has more apps, multitasking idea was taken from either WebOS or BlackBerry PlayBook, and last but not least the car integration idea was actually bought up first by BlackBerry and QNX. Those are things I've examined from WWDC. They might have added their own stuff into the phone but the rest weren't innovated ideas made by them. Some people didn't even like the swiping idea of BB10 OS and now the iPhone has added it to its OS update. Steve Jobs once quoted Picasso by saying "Good artists copy, Great artists steal".So this proves my point. Why do people praise them when they haven't invented anything?

Is this a sign of definite cheating?

I'm new to the forum. But my name is Bradley. I'm 28 years old. I have been in a relationship with my girlfriend for almost a year now. Everything is going great. Then I was using her phone the other day because my died. And I seen a number to a guy named "Jonathan" it showed in recent calls, she had called him late at night for and hour at a time.So, here's what I did. I wrote down his number, and I texted him from my buddies phone (a phone number that my girl doesn't know ) and I told the guy (in the text) that his number was on my girls phone and he had called and texted her phone and I asked him why and who he was. I sent two different text. Two hours apart. And dude never ever replie back. And I know he got the text because it was from iPhone to iPhone apparently and it shows when they are read. He never replied back. So my question is, from another guys point of view why wouldn't he reply back at all? If it were me I'd at least say something back. But this guy didn't say anything and won't answery text.So, please don't be rude or leave smart comments about I should I have done this or shouldn't have done that. Just please answer the question I'm asking honestly. If not, then please no reply at all. My question is why wouldn't a guy answer a random text like that back? I'm a guy, but I don't know why a guy wouldn't answer back. So it has me wondering even more, if that's an even worse thing.
