Recently read an article of Microsoft said that is hit to 1 million registrant for window insider program to test and feedback for beta window10 before it is official launch in the 2015, this is amazing and so excited news, by looking on the numbers, you will know window 10 will be the future, all hardware device have to updated the driver to compatible to it (hopefully it is not much change on the hardware support), if not then our wallet have to spend again to run this upgrade, that's why i hate update the OS(operating system).
