To put it simply no one can match the iPad because no one can match Apple’s prices with a tablet that matches its features:
When better equipped (though bulkier) netbooks can be had for $250, tablet-makers need to set their sights below $200. There is just one problem: the cost of the components currently used comes to more than that. According to the market research firm iSuppli, the basic TouchPad cost Hewlett-Packard $306 to build.
At the moment, as The Economist correctly points out, Google’s strategy isn’t working either:
But the ultimate killer feature that Android and other tablets have failed to replicate is the care Apple took from the start to ensure enough iPhone applications were available that took full advantage of the iPad’s 9.7-inch screen. Today, over 90,000 of the 475,000 applications available online from Apple’s App Store fully exploit the much larger screen size. By contrast, only a paltry 300 or so of the nearly 300,000 apps for Android phones have been fully optimised for the Honeycomb version of the Android operating system developed for tablets—though many of the rest scale up with varying degrees of success.
There simply isn’t enough incentive at the moment to develop applications which fully take advantage of Honeycomb. And Google doesn’t appear to be pushing developers to do it.
