Serious this debate is still on going?
Anyone with some sense sees the following about Windows 8:
Primary function: Tablets
Secondary function: Laptops
Tertiary function: Desktops
This OS release was never meant for the main stream PC base, but they are hardly going to release a Tablet OS version. The whole point of this is to present a unified OS for near all device formats.
This release was never meant for the main stream PC base and to consider other wise is a waste of your time. The only thing I can find this useful for is HTPCs where you want a simple interface for movies and such.
If you really need to upgrade just disable metro and go back to classic desktop, simples.
