Exepsnive, but the price will come down
Steep price. If Apple ever releases the so-called iPad Pro, I can actually imagine it undercutting this price, since I doubt Apple would charge a $400 premium for the larger screen. (That's assuming, of course, that the iPad Pro is simply a bigger-screened iPad Air, rather than some kind of new form factor; there've been rumors, for what they're worth, both ways.)
But there isn't an iPad Pro right now, so I suppose Samsung has some space to experiment with pricing. Like several people in this thread, I'm not sure many people will drop $1000 on a Samsung tablet and accessories when a wide variety of Windows convertibles are available for substantially less. Windows 8.1 devices aren't popular, of course, which is probably why Samsung feels bold-- so I guess we'll have to see. Will Samsung's UI and the promise of Android apps trump the productivity merits of Windows tablets? Since this device is aimed at professionals, I'm not so sure.
My guess is that this tablet will settle into a lower price point before too long.
