I'm going to stay with 8.1 for a while but as far as the privacy/intrusion part, I would say get used to it. Appears to be the way society is headed. Everything about you, likes/dislikes, family history, what you buy at the grocery store, on and on, will be stored in the cloud. What do you think is being done with all the data being collected via those store membership cards? Heck, look at all the very personal information people willingly post on Facebook, Twitter, etc. I honestly think what MS is doing with 10 is only the tip of a very big iceberg.
