If display size and resolution didn't matter to consumers, all the manufacturers would be selling smartphones with small crappy screens and they would be competing based on price and other features. Every year you would be able to buy a new smartphone with the same display as last year that was cheaper and had some other features (eg., faster cpu, more bandwidth). There would be no tablets. But that's not what happened. Since the iphone was first introduced, we have seen a relentless push for larger displays with more resolution. It's the two features that manufacturer's KNOW that the consumers want and are willing to upgrade for. Just look at the come-on for the latest smartphones and tablets... The Apple home page describes the iphone as "the biggest thing to happen to iphone since iphone" which is them finally responding to the fact that the larger displays on their Android competitors were eating their lunch. Or the ipad as "ipad with retina display". Clearly Apple thinks that the single most important feature of the ipad is that it has a high resolution display --- it's so important they made it part of the name of the product. Now to the Google Nexus 10... "With the world's highest resolution display, all new multi-user features, immersive HD content and the best google apps - Nexus 10 has something for everyone". The Google marketers aren't as skilled as those from Apple, but even they figured out the single most important feature of the tablet is its highest resolution display.
And if display size and resolution didn't matter, consumers would be buying 27" flatscreen tvs with 480p resolution because they were so darn cheap and convenient. But they're not. Instead of saving money by buying a smaller cheaper more convenient lower resolution model, consumers want larger monitors with more resolution and they're willing to pay more for it.
P.S. Nobody's asking you to throw out your TV. They're trying to find something to offer you that you're willing to pay for. Isn't that ideal?
