The only way I'll get windows 8.anything is if it is on a MS surface pro. I have tried windows 8 on a brand new laptop and it was infuriating to use. They made almost EVERYTHING harder to do from a desktop user perspective, as far as I could tell after using it for 3 days. My desktop didn't need a paradigm shift towards the same level of uselessness I find that most tablets bring to my daily computing needs. The only tablet that could truly replace my computers is a MS surface pro (or nearly identical equivalent), so maybe win8 would work for me on a tablet that was actually capable of replacing my laptop and desktop.
Putting a tablet OS on a desktop or laptop is stupid. So I'll skip win8 just like I skipped vista. If they never release another desktop OS, I'll probably switch to apple or Linux on generic PC hardware. If the BIOS gets locked down to only run windows, then I'll probably quit buying computer hardware altogether and just use my phone for everything.
That is exactly what I have purchased. It literally replaces all computers except my gaming rig for me. We used to have my gaming rig, 3 laptops, and an android tablet. We wanted to upgrade, so we went with the Asus brand equivelant to the surface pro. (the Asus brand is a little smaller, lighter, and is passively cooled, with better battery life, plus its cheaper). We bought 3 of them. one each for myself, the boss (wife) and our daughter. We have since dumped all PC's except my gaming rig... with the keybaord dock hooked up, the tablet becomes a small screen laptop. Then, you can hook it up to a monitor or TV for a larger screen if needed. etc etc. It is a full blown computer, in tablet form. Nothing watered down or anything. As far as Windows 8 goes. I tried it and hated it on my laptop. However, I absolutely LOVE it on this tablet. It is definitely touchscreen optimized. The solution IMO for microsoft, would simply be to allow the user to select metro, or "Classic" mode, that way they can pick and choose depending on their hardware, OR hardware configuration (such as automatically going to classic mode when docked to a keyboard, but switching to metro if the tablet is standalone, etc etc)
If they did that, they would have a definite winner in Windows 8. As it is? Windows 8 is only a winner for tablets.
