i think osx isnt really made for a tablet. (niether is xp, or vista by the way) if you really want a mac tablet or something of that sort, just get Axitron's modbook but, as said before, it is somewhat expensive. an iphone, or an ipod touch could really just be enough
I agree with you somewhat. Tablets really need their own dedicated user interface. I don't think Apple will make a tablet, but were they to, it should sport a more specialized tablet-friendly UI, and not Aqua, because Aqua is a very point-and-click-friendly UI, but not one I want to touch. I don't want iPhone OS - which is built for a small screen. Some sort of hybrid, I guess. That won't happen, of course, because it would mean everyone would have to repackage their applications to run with this modified UI.
If Apple does release a tablet, I expect something along the lines of the MacBook Air, an absolutely beautiful product but too expensive and compromising too much to be worth it (in my opinion, at least. I would rather have a MacBook Pro than a MacBook Air with $200 left over. I realize that the MBA is very popular, and the people I know who have one love it so, but personally I don't get it). The people who would be interested in it would be deterred by its mediocre specs, and its lack of upgradeability. It would be less than an inch thick, but with everything soldered on, it would likely have little appeal and be pulled relatively quickly.
As for the Modbook, sure it's cool, but I honestly find it ugly. The silver and white kind of clash. An Apple product would likely be much more well integrated, but unless they provided a Mac touch pro, with a large screen, and actual decent hardware, I'm not interested.
