Well, considering it isn't designed as a primary content creation device, not a surprising result (which so many of us have tried despite knowing this). Next experiment: To consume content primarily on a non-tablet non-phone for a week. (It will fail a comparable way.) No matter how much you squeeze an apple, no matter how tasty the results, you won't get orange juice.
The convergence of the PC and the tablet is inevitable. The awkward solutions that have been presented thus far are simply prototypes. We will eventually get it right, and when we do, the resulting experience will seem like it should have been the obvious choice from the start. We already see the value in responsive web design, which is also in it's infancy. Eventually, we will have responsive operating systems, appl…

Long term ... sure maybe a 12 core tablet is possible, but that is really long term IMO.
