Look at "smartphones" and touchscreen phones before the iPhone, they were horrible. Unresponsive, clunky, cheaply made, bundled with awful software, and couldn't load custom software like apps from an App Store.
Not sure where you're from, but in the USA, carriers did not restrict smartphones to their own stores. You could buy or download apps from anywhere, both native and J2ME.
When the iPhone came out, it was crippled in many ways compared to the smartphones of the time. Many others had 3G, GPS, MMS and video recording, all of which the first iPhone was missing for at least a year.
They also third party native apps such as Google Maps, TomTom navigation, medical dictionaries, Slingplayer TV, and of course games. Some even came with built-in app stores such as Handango (my favorite), who sold apps for every type of smartphone.
...if Samsung is such an innovative company they'd have done them first or have files to back up the R&D years earlier.
Samsung
did have R&D files (see sample below). Judge Koh banned them over a technicality at Apple's request.
Apple also managed to block any evidence from the Samsung F700 designer, which would've proved certain of their claimed unique design elements predated the iPhone:
Apple's lawyers fought against Samsung showing it, claiming that, "
Going into the design history of the F700 in particular is extremely prejudicial because the risk is high that the jury will consider the F700 as evidence of independent development, invalidity, or non-infringement regardless of whether or not Samsung encourages them to do so. "
Well duh.
If Apple truly believed they were in the right, why would they be so afraid of letting juries see prior art? The answer is, they had already lost design and patent trials in Europe when such evidence was shown. They also lost an injunction request in the US partly because the appellate judges DID have access to everything (unlike the jury).
Apple knew they were not first to invent everything they claimed. They were the first to popularize. Big difference, although they certainly deserve every credit for the latter.
