Re: but Apple will probably wait ..
"Touch-screen smartphones and proper tablets (not just a computer stuck in a touchscreen unit)? Siri? iTunes?"
Touch-screen - nope (though if you said multitouch, you'd be right). They didn't popularise it either (the most successful smartphone of all time is from 2009, and a touchscreen - it wasn't made by Apple, but by Nokia).
Proper tablets - by which you mean smartphones rather than computers in a touchscreen. Well, they already existed for years - most notably, smartphones. There were also "media players" which had larger screens and did Internet, videos, apps (including ones that run Android in 2009). In the early 2000s, we had PDAs. Tablets that weren't "computers in a touchscreen unit" existed for years, we just called them by a different name, and originally, "tablet PC" was only used for PCs. That's not being first, that's playing with dictionary definitions.
Siri? A trademark for voice recognition that existed for years on other platforms. And even Siri itself wasn't invented by Apple, but bought out.
Yes, they were first to market with itunes, that's because itunes is an Apple product, just like Nokia were first to market with Lumia phones, or MS are first to market with Windows.
"Someone selling a few mp3s online doesn't really count"
Aha, here we have it - Apple were first, except for those who did it before them. If we can discount those who sell less, then we can discount the early iphones, as Apple sold far less phones than several other companies. We can discount MacOS's GUI, as Windows sold far more. And we can discount ipads, when Android tablets are now starting to sell far more. We can also discount the first ipod as it sold poorly compared to the competition (it wasn't until they added support for Windows that it started to sell better).
"And a fully touch-screen phone is /was a pretty bold move."
Not as bold as those doing it in the previous year.
