Microsoft is making the smarter move to ship Windows 10 retail via USB Flash Drives, with not a Windows 10 DVD in sight.
The new operating system is already available for pre-orders on Amazon for the prices of US$120 for Windows 10 Home and US$200 for Windows 10 Pro.
Shipping date for both of these OSes are scheduled on August 16, almost 2 weeks after Windows 10 launches. The target market for these are probably people who are not eligible for the free upgrade (Windows 7 with Service Pack 1 and WIndows 8 users) or for those who simply feel more secure with a physical copy.
