In defense of hardware, it's always kind of bothered me how people like to slag on hardware as useless, but what is the most successful company in the world? It's Apple, a hardware company through and through.
I would also point out in phones, that I follow, I'd argue Samsung has partly succeeded on hardware. The Galaxy line does so well at least partly due to their super Amoled displays (that nobody else seems to have, although recently the latest Droid is said to have one, which I found a little odd, guess Samsung licenses them?).
Owning a superamoled phone myself, I can say it can be one of those things that once you have it, you refuse to go without it. I'm fairly locked into Samsung now because I really dont want to go back to poor LCD displays.
And they keep a blistering pace, Galaxy Nexus is a hardware beast, and rumored Galaxy S 3 even more, quad core 2 ghz, 720P, superamoled II, 1.5 GB RAM, these are all first and foremost monster hardware specs that set the pace. But especially the super Amoled displays have differentiated Samsung phones, and nobody else has them (except again that recent Droid being the first exception).
Anyways just trying to make the point that I think hardware consistently gets short thrift as to it's importance. Again, it's what Apple built it's whole empire on, really. You could say "user experience" but hardware was an integral, perhaps most integral, part of that. When I look at Macbook Air's in the store, I'm not impressed with the software, but rather how incredibly slick the hardware is. I dont like Apple, but I still say "wow, that's pretty neat".
But there's two sides, Vita is obviously great hardware, but I suspect it's entering a market where it wont matter.
