The most distinct aspect of Windows 8 is what's known as the "Metro UI," which allows users to have complete customization on their home page, including widgets, RSS readers, weather information, date/time, etc...... since this is such a revolutionary new platform, Microsoft wants to scrap out all remnants of the "old-school" look and feel.
