That's what netbooks offered and still do. Perfect for touching up a presentation on a long flight without having to double the amount of carry-on with a fracking laptop case/bag. Macbook Air provides precisely that functionality but at $1200US compared to the average netbook's $200-300. Tablets? They are entertainment, _not_ working machines. MS Surface might seem like a good working tablet, but it's priced as a laptop; MS successfully co-opting both the network and tablet markets while extorting an unreasonable price. Once again, big companies hijacking affordable computing from users.
