If you look at the retail outlets you don't see tablet PCs on the shelves anymore. It seems to be be a great idea that is trotted out every few years. Yes, there are a few that want this but it's not a percent point of the market so the units sit idle in the inventory and soon get removed.
With such market performance it would be a mistake to offer such an unit unless all the costs were rolled into the unit's selling price. Which may make it a non-starter as well.
Research this a bit more to see why things are the way they are.
Apple has always been the first major computer company to adopt new technology(think USB). Curiously, they didnt jump on the burgening tablet market, so my hypothesis is that Apple has been developing a version of Leopard that is specialized for use on a tablet because no one has made a true tablet OS and Apple wants to get it right the first time. Just think how cool it would be to pull out a brand new x86 based iBook and then twist the hinge to write down notes with the world's most advanced OS, computers will never be the same again.Anyways,Is it possible that Apple could introduce a special model of their notebook line with Intel processores and a tablet OS
