Windows 8 will be run as two different systems using a common interface. The first released will be the Intel type which appears to be Windows 7 with a new Touchscreen and can run legacy applications. The units demonstrated that these are clearly not designed to compete against iPads and Androids as they are very heavy and require a fast CPU with a large amount of RAM. The other Windows 8 will be a new system running on ARM phone chips and will not run Windows 7 Applications. This one will be designed to compete against Apple and Google. Interestingly Apple said in court when suing Android manufacturers that they should dump Android for Windows Tablets because they don't look like iPads and iPhones. Obviously Apple are more worried about Android than Windows. Android phones now have over 40% of the new market compared to iPhones 25%.
