I mostly agree that Samsung (and the like) are doing real hardware innovation, but I think Apple's innovation is more a matter of actually creating a computer "Appliance" that people use and feel comfortable with, in the same way as a toaster over.
Yeah, sure, if you care about the exact temperature, or want to play with convection oven circulating speeds, they won't expose all the controls you want, but if you find it all intimidating, and just want to hit a button marked "Toast" and have the oven do its job, then you might like it (especially if its "stylish").
Not saying I agree with all the lockdown, but their modus-operandi of making things "appliance-like" while bucking most geeks feelings about it, are MUCH MUCH better aligned with what the vast majority of users want.
Heck, my mother-in-law recently got an iPhone. For the first time since she got a cell phone (at least 15-20 years), she's now picking up voice mails, making text messages, and taking pictures (still hasn't learned how to attach them to Messages yet). Not saying she Couldn't have learned on any other phone, but she hadn't yet.
(note: I think all of these lawsuits are ridiculous, but I also think Apple has done a fair amount of innovating in putting together a cohesive product that IS more than just the sum of its parts)
