Mr. Sobotta tells a longer story over at The Guardian of his 20 years of experience at Apple, and Steven Frank more or less rounds up the bullet points in a Macworld rumor call-out post. To sum things up: the idea of a tablet Mac is cool - really cool - but the fact of the matter is that the tablet PC market sucks. And by 'sucks' I mean "it's downright horrendously dismal." Steven also reminds us that Apple hasn't really been making products for unidentified markets for about a decade now. Sure, there are a big handful of Mac Photoshoppers that would love to be able to craft their next Fark submission with a Mac tablet on the couch, but the unfortunate reality is that Apple - already a niche company - would need a *lot* more interest in an über-niche product like this to make it profitable. To make matters worse, already established industries (like the medical field) *still* aren't touching the tablet PC products that have been on the market for over two years now.
Steven lists a lot of other good obstacles that simply don't seem ripe for Apple to tackle anytime soon, and Mr. Sobotta certainly offers some commentary from behind Apple's well-guarded veil as well.
Which brings me back to the intriguing ModBook announcement from OWC. Apple hasn't made the idea of a tablet Mac work just yet (though who knows: maybe next week could prove everyone wrong), but OWC apparently has. Next week should be a very interesting one, to say the least.
