well, I don't think so. Apart from iPad not one single tablet made any significant succes. And we already had win7 tablets. And long before iPad there were windows tablets/convertibles. I had one and I always used it as regular laptop. And considering all those cases with keyborad for iPad, Asus transformer and now Surface, majority still wants a keyboard.
I can see some advantages of Pro model but I think that price will be very high. And I would always rather give a 2-3 benjamins more for a 13 or 14 inch ultrabook than this.
And the one with winRT Who will buy windows based tablet only to realize that there's no apps for that. And today number of apps is everything, no matter how many of them are stupid or useless or just poor copies of succesful ones but they still counts.

I think that it will be succesful as lumia is
