I don't think that the Surface Pro will overtake the iPad overnight, but it should have Apple worried. Not worried about sales numbers or consumers changing their spending habits and buying something with a Windows logo on the back instead of an Apple, but in the long-term it's going to have repercussions for the Cupertino-based electronics giant.
Until now, Apple has not had a true competitor in the tablet game - sure, we have Samsung and Google, ASUS and Acer, and many others - but no one has even come close to competing on the scale that Apple plays on.
Microsoft won't win with the Surface Pro, but give it a generation or two of the Surface line of devices - the introduction of the next-gen Xbox, and a cleanup of Microsoft's services as a whole, and I can see Microsoft getting right back into the game.
The only other problem Microsoft has is Google. Google's tablets are getting very, very good, and their Project X labs is designing some great things. We're seeing the fruits of their labor with Project Glass and X Phone, so 2013 should be a stellar year to be a tech junkie.
The kicker to the Surface Pro is that it'll set you back around $1000 for the 128GB version. It's about $100 cheaper for the 64GB-based Surface Pro, which isn't too bad. This is much more than the iPad, but a 64GB iPad is getting up there and close to that price anyway, and it's just a tablet.
The Surface Pro is much, much more than that - and I think people will be singing a new tune not only about Windows 8 when the Surface Pro lands, but Microsoft as a company, too.
