Well, the phablet form factor - the Samsung note range did create (or perhaps reveal) that particular market, which Apple eventually decided to move into.
Software-wise, I have no idea as I've never really used an iPhone.
If you're going to credit Samsung for the phablet form factor then you need to credit Apple for the iPhone and iPad form factor it built off, and so on and so forth.
I'm not the initial poster and have no interest in defending the initial claim about who contributed more, I just wanted to give one example where Samsung lead the market and Apple followed.
Presumably we should also be giving credit to MS for their early pushing of the tabletpc form-factor. It's all evolutionary...
And no, Android features Apple copied from Google don't count.
