For the first time, we are still relatively in the dark when it comes to the new Windows platform's pricing model. So far, all that Microsoft has revealed is that customers who purchased a PC in the last couple months will be able to upgrade for $15, and all other Windows XP/Vista/7 users will be able to snatch Windows 8 for $40.
However, those are limited-time promotional offers, and the full prices for the updated OS have yet to be revealed.
Windows 8 will be unlike any previous version of Microsoft's operating system because it will have a dedicated focus on tablets that will be separate from the standard PC version.
As such, pricing is not going to be as standard as it usually is.
Microsoft has a lot of ambition with Windows 8, and with a complete interface overhaul and functionality up the wazoo, it does have a chance to make a splash.
The most distinct aspect of Windows 8 is a special version of the user interface which allows users to have complete customization on their home page, including widgets, RSS readers, weather information, date/time, etc.
In addition, since this is such a revolutionary new platform, Microsoft wants to scrap out all remnants of the "old-school" look and feel. Instead of a Start bar, hovering your mouse over that corner of the screen will allow you to swap between the Metro UI and the traditional desktop. For the mobile version of Windows 8, the new UI will be the default interface.
Surface will be Microsoft's own first-party line of tablets powered by Windows 8.
