I've never used 8, but I liked 10. I especially liked the built-in anti-virus - there was noticeable performance improvement once I got rid of the 3rd party stuff. Absolutely hate 11 though - I'm planning on rolling back soon.
Yeah, the last time I posted about AI stuff I got my first-ever negative net votes here, but it was news and I posted it. Same here. Alvin Ashcraft also posted a link to it, and I said to him that from what I've seen so far, this isn't going to work out any better for them than it did last time. Maybe next time they might learn to ask developers first, BEFORE saying "Hey developers - we need you!".
