The whole 'cloud' (which is just a new word for network server share system... The catch-phrase word of the decade... and I'm already tired of it...) and the push for it with W8 is the biggest thing keeping me from even thinking about using it. Let alone businesses. Obviously there has to be some sort of block to it cause internet file sharing is against most businesses security practices... And that's exactly what this would be... Plus I can see the first big lawsuit already... 'World sues Microsoft over privacy hack'... And you know if/when it happened, it wouldn't be no small settlement... Any lawyer who would take it is seeing dollar-signs... (another problem in the US, but another topic....)
Anyhow, point is, I'm going to stay with W7 until we can tear it down and be sure it's entirely local-only... Company isn't even past XP yet and they're already trying to sell W8. I don't say this too often, especially in the tech world, but they need to slow down; Seriously. They're charging too much and instead of the OS going for extended periods with service packs and such to keep it updated, they're rolling out entire new OSs to 'purchase'... And that's not even getting to the other problems of their 'new' and 'improved' gui which is horrid and useless for traditional controls... W8 should be called W7-Tablet or something... Even though you can turn a lot of that junk off, there isn't the old standard start-menu type control system to return to... it's just not there all the way.
