"with little or no serious upgrades" - funny, most A.org posters would object to that, but I'd agree. Dave and company's enhancements were minor.
If you take the time to watch Dave's awesome talk, he says clealy that the C= engineers were constantly trying to push the technology... But the C= management would cancel any project that looked even slightly expensive... We were stuck with OCS for 5 years... Followed by ECS, and as Dave explains in the video, a very slight upgrade to AGA... Which was basically ECS where the C= had managed to figure out how to double the data rate on the bus for no extra cost...
The iPad isn't that impressive. And, as stated before, the elements that made up the Amiga had their foundations in other company's research.
I said nothing about impressive, I answered your original assertion of original. The only thing impressive about the ipad (other then the battery life) is the quantities in which people purchased it...
The iPad was an original approach to building table computers, by taking well established technologies and put them them together in an original package.
Edit - Then again, looking back over my posts, my attitude in this thread has been pretty fecal eyed.
I like old Sun systems for similar reasons, and they didn't invent a great deal of their earlier technology either.
You don't have to like Dave Haynie to watch and enjoy the video
