It’s getting wearisome, but I feel I must, at least somewhat longer. I’m talking about posting links to stories evaluating the various tablet devices on sale now, with an eye to the holiday season. Today’s item is an article in the Times by its technology editor and it’s aimed at sorting out the various KINDS of machine, according to what they will and won’t do. It’s interesting too in that it makes the prospective purchaser focus on what the actual need or desire is that the gadget is supposed to fill. No more of this “Oh, Bob might like one of those tablet things”. Well those tablet things break down into several sub-classes, each of which has capabilities and price tags that vary often greatly from the others. It’s an effort on the writer’s part to help people make good decisions, but they have to cooperate first.
