With the decline and fall of CD and DVD-ROMs on-line distribution has taken a huge step forward, meanwhile sometimes you can't be online so how do you install something ? Well, Microsoft will sell Windows 10 on USB-sticks, and yes that is the next logical step.

On Amazon you can already order the sticks, however the delivery time will be August. Microsoft Windows 10 Home will cost 119 USD, Microsoft Windows 10 Home Pro is a steep 199.99 USD. In the USA these prices are level with Windows 8.1. Microsoft Windows 10 Home would cost 135 EURO in the EU, 20 EURO more expensive opposed to Windows 8.1 The Pro version will cost 165 EURO.

After a quick check on EU stores, the USB-Stick versions are not yet available for pre-order. Obviously you can upgrade for free from Windows 7 and and 8.1
