Their are tons of rumors of a Samsung 2560x1600 tablet, that's gonna be "retina" enough for Refrigerator..
Please don't continue the cycle
In all seriousness, while I'm all for pushing resolution I do have to question the value of such a device
today ... particularly in a 10" device.
With current processor and battery technology, the benefits of going that high will likely be outweighed by performance loss. When you start moving to ultrabooks and laptops though ... then I could see an argument for the benefits being worth it. Obviously moving forward, as transistors are die-shrunk and batteries improve,
then there's really no reason to not do it even at 10".
Only read a bit of the article ... but I'm not so sure I agree.
Regarding the Samsung, it's their first 7.7" AMOLED screen (produced on their new gen 5.5 fab line). Of course it's expensive. It isn't indicative of their long-term pricing strategy, it's simply a result of low yields. The bleeding-edge screen tech has yet to mature.
For the Sony, it's obviously a niche product. It's a novel idea, but serves a pretty specific audience - those that want a bigger screen on a pocketable device. Obviously the dual screens and custom nature mean build costs prevent it from being an entry-level device. And since (I assume) they realize the audience isn't going to be huge, it's only logical to also place a decent margin on the item since those that want such a form-factor have no alternative. If someone wants its form-factor, they're going to be willing to pay for it.
Certainly if demand proves to be good moving forward, they can always tweak margins based on volume. But I really think they're placing it at a logical position right now.
In both cases, iPad costs are really irrelevant. The Samsung is simply gonna cost what it costs until yields improve on their tablet-sized OLEDs ... and the Sony is targeting a specific use-case that's outside iPad's to begin with. I'd argue the editor is a bit clueless if anything. Not everything tablet isn't inherently tied to iPad.
