I knew from the get go that Microsoft would not offer Windows 9 for free. Its two main income streams come from Windows and Office, and while MS has other irons in the fire, dropping payment for those two products would severely hamper research, product innovation and diversification.
Having said that, however, it may be that Microsoft sees the need to heavily discount Windows 9 in order to remain competitive in the OS market. Both Apple and Google have made ground in the OS market, so MS may see the need to sacrifice some profit to increase market share, and in doing so it can reap profits from its other applications made for the Windows platform.
I am very much looking forward to the release of Windows 9 and its improvements upon Win 8. That is not to say that I don't like Windows 8/8.1, because I do, and very much so. However, I believe Windows 9 will bring some new and exciting developments that not only build upon the innovation Windows 8 brought us, but go well beyond and then some. Given that UEFI was relatively new when Win 8 was being developed, and that CPUs have come a long way since, I believe Windows 9 will yield significant speed and stability improvements, among other things.
A whole lot of people complained, bitched and bellyached about Windows 8 and how unusable it is, but really, it is the stepping stone to a much improved platform in Windows 9. Furthermore, I wouldn't take the sales figures for PCs as being a serious decline and/or ultimate demise of the desktop PC. People already had PCs when tablets hit the shelves, so it was natural that they'd want to check out the latest in tech, rather than buy a new desktop PC.
The thing is, tablet sales have leveled off and many of those PCs people had before will need to be updated/upgraded in order to take advantage of the latest in OSes and software. I therefore believe things will come a full circle and desktop PCs will again be the flavour of the month for some time to come. I believe this because tablets simply do not have the processing power to achieve many tasks that a desktop PC can breeze through, and to make tablets more powerful and capable, they would have to become bigger, bulkier and more clumsy, and people do not want that in a portable device.
So long live Windows and desktop PCs
