Selective bolding on your part. Without the bolding the statement makes perfect sense.
With the appropriate applications, they are productivity devices for very specific usage. However, for generalized usage they aren't fast enough yet. You need more speed for that.
The Intel Surface Pro would easily be fast enough, but unfortunately, at $999 it's more expensive than it needs to be.
I'll have to wait and see the full true spec list - but I imagine $1000 for a good i5 full Windows tablet that can function like a bastard step child of the MB Air and Ultrabooks when needed, and be turned into a wholly different style of usage in a true slate form... I'd be cool with that.
Granted, I'd like to spend less than $1000 for such - $800 or $900 - but with the internals and full Win8 x86 OS that that device brings, I'm not holding my breath.
Plus, full 1080p touchscreen plus Wacom digitizer?
I'm already imaging just how much use this thing would get from me.
Anything over $1000 - no way. Under 900 before tax? If finances line up, day one purchase.

That $1000 price point will make be scrutinize it ever so slightly, wait for technical reviews and whatnot... but I'm thinking yes, do want.
As long as the full hardware package isn't severely lacking. It won't be a workhorse playing games (I have my desktop rig spec'd for that), but a decent GPU (likely Intel - perhaps one of their better ones?) for tablet-style entertainment/consumption would be nice. Using it vertically to read things, perhaps watch youtube and browse around, use it for any MS Office tasks if I want to be a little more comfortable or am away from home (could replace old Pentium Duo [or whatever it was] laptop I had for note taking in school.
Such a tablet will not be iPad-competitive pricing, and really... isn't even designed to compete with the iPad or other ARM-based tablets. This is something a little more special - their old x86 tablet approach, done right (with an OS designed for it). I always wanted that but they always sucked, quite a bit before their time for consumers.
Their ARM-based WinRT model, definitely needs to be, entry-level, less than $600. If they only have one model, it needs to be 500. If they offer a 16gb version or whatever, or two models one way or the other, one needs to be $500 or less if they expect sales. But a decently-speced machine will be good at $600 imho.
But unless Nvidia has something insane up their sleeves, I won't pay that much for a quadcore Tegra 3 tablet - hell no. The GPU is lacking, massively.
Too many awesome SOCs are due within the next 12-18 months to sink that kind of pretty penny into a device with that particular SOC... but, I'm not the average-minded consumer.
IMHO, any tablet priced around the iPad, needs to, at the very minimum, go toe-to-toe with the hardware inside the iPad.
