I'll be the first to admit that tablets aren't my thing, but let's call a spade a spade and an expensive toy an expensive toy. Tablets are pretty much one of those things you own because it does neat and entertaining things, not because (like traditional computers) it is a practical device for any but maybe a few specialized varieties of serious productivity or because (like phones) it provides a means of instant communication most people insist on having on them at all times. Tablets don't really satisfy a specific need. Most people already have a variety of devices which individually offer all the functionality of a tablet, usually with greater effectiveness.
Still, perhaps I did not communicate effectively the tone I intended, which was one of grudging admiration for the accomplishment of a company I generally don't like. No other company could have ever made people want such an frivolous device--few, in fact, are having any real success following the leader, for that matter. Certainly Acer's line of reasoning regarding their comments on tablets reflects some of what I've said. The rest is because the terms 'tablet' and 'iPad' are interchangeable in many people's minds, and that's just not a mountain most companies will successfully scale.
