Microsoft has finally released more information about Windows 8 on ARM, and it included this interesting titbit:
As we mentioned, a portion of Windows is generally built with code that can be made to work on ARM in a technically straightforward manner. These subsystems include the Windows desktop and applets and supporting APIs, though we needed to significantly re-architect all of them for better resource and power utilization. In fact, here is an early photo of an ARM device (an early Windows phone) running the full Windows desktop. Early in the development of WOA, the only hardware we had were existing ARM devices such as phones (ARM tablets didnâ€™t yet exist). We just thought you would enjoy a few fairly early photos I captured of debug WOA all loaded in RAM (unretouched). Note: This is not a product plan or even a hint at a product.
Given that full Windows was made to run on an older generation Windows Mobile phone, I think the arguments that Windows Phone 8 will be too heavy to run on Gen 1 Windows Phone 7 hardware has just taken an arrow to the knee.
Manos drew our attention to the task manager from the picture above, which shows Windows 7 running in 256 MB RAM with 90 MB free. Pretty impressive and another sign that Gen 1 handsets will be able to handle Apollo.
