Microsoft has reached the release to manufacturing (RTM) build of Windows 10, with its official release on July 29 right around the corner, but how will you be buying the new operating system? On a disc? Upgrading from your old installation, or on a USB flash drive?
Windows 10 can be pre-ordered on a USB flash drive on Amazon, but these drives won't be shipping until August 16. This date can change at anytime, so you could receive it earlier than that. Windows 10 Home is $119.99, while Windows 10 Professional will set you back an additional $80, for a total of $199.99.
