Re: New features != "must have" features
"Apple was the first to put all the stuff in the first paragraph together into one phone"
It was the first one to have multitouch, and all of the other things were fairly standard things, so it trivially follows that the iphone was first to have the complete set. But that doesn't mean it was actually first with those other things! This is just cherry picking your featureset, and I could do the same for any first by another company. If you're doing an AND of features rather than an OR, then simply being first with one of those features, means the product will also be first with that one feature AND many others.
E.g., for the first phone that could do Wifi (a Nokia?), I could say also "It was the first phone to do Wifi, and [long list of bog standard but useful features]" - well no, that's not anything new, I've just rephrased the being first with Wifi. Similarly I could say Nokia are the first company to do GPS for maps/directions, full desktop browser, multitouch screen, wifi, MEMS/gyroscope sensors, a camera of sufficient quality to produce acceptable pictures when picture-taking _is_ the goal of one's day, the ability to install third party apps that have access to an API comparable to PC apps are a must have in any smartphone. By subtely upping the camera requirement, I've moved it back to Nokia. Same if I included sat nav.
The 2007 iphone couldn't even run apps at all. Does IOS really run exactly the same browser as desktops? Not that I see why that matters - Nokia don't have their own desktop browser, so that's an unfair comparison. Decent browsers were available, like Opera Mobile. Since browser choice is a personal preference, I'd much prefer a platform that let's me use any browser I choose.
"Since then, there has been nothing added to smartphones, either from Apple or Android, that contained something that nearly everyone finds useful and has become a must have for every phone made."
I'd agree that many things being added are gimmicks, but I'd still include sat-nav, a decent size screen (4" minimum) and resolution (800x480 at least - even Symbian's 640x480 was better than the iphone) as important too, so for me phones didn't mature until around 2010-2011, and it was Android leading the way (with Symbian the contender). The 2007 iphone wasn't even close, with its lack of apps, 3G, and even copy/paste.
I'd also add that multitouch is as much a gimmick as any gimmick today - it's useful, but not revolutionary. I want to use a phone one-handed sometimes, and a multitouch UI is a much bigger prevention than large screen sizes. If anything, credit should be given to the little-publicised one-touch zoom that Google have started to introduce into Android (double-tap, then move finger up or down - annoyingly it's not OS-wide, and confusingly the zoom direction in maps is reversed to that of Chrome!)
I agree with your last paragraph, but doesn't that apply for multitouch too? Apple didn't invent capacitive screens, they just happened to be first to market for phones with that one feature.
