"Memory performance of the iPhone destroys that of the S3"
The iPhone is only slower because the CPU is down-clocked. The Note is obviously faster in that department because it has a quad-core. Memory performance of the iPhone destroys that of the S3. Plus the S3 has a crap screen and crap build quality. The Note 2 has an even lower ppi than the S3, so I'd have to imagine it looks even worse. Android phones are definitely catching up in terms of OS quality, but they still have strides to go to improve on all the little things that Apple constantly beats them on.
iOS, like OSX, requires much less memory than Android or Windows. It is a simpler OS and doesn't have nearly as many features and services to run as Android or Windows. That is why Android and WIndows phones require more power."Plus the S3 has a crap screen and crap build quality."
I don't know what S3 screen you have been looking at, but the S3 screen is not crap. Sorry, I had an iPhone 4S, and the S3 may not be a Retina display, but is not crap. It looks amazing. The colors are simply beautiful. As far as the build quality of the phone, I won't argue with you on that one. Yes, Samsung loves their plastic and yes, the Samsung phones build quality is not as solid as the iPhone, but they are still good phones. Samsung must have a reason to use plastic. Maybe to prevent the phone from over heating too much? Maybe it's cost-effective to the customer? Their reasons they have."The Note 2 has an even lower ppi than the S3, so I'd have to imagine it looks even worse."
Are you kidding me? I get the feeling you have never had a Note 2 or S3 screen in front of you. The Note 2 screen is super beautiful. There is nothing wrong with it. Again, it may not be Retina, but its very close. It's Super AMOLED+ and unless you have bionic eyes equipped with 5000x Zoom, I don't see how you can tell the difference. I have 20/15 vision and I can't see any quality difference between the S3 screen and the Note 2.
