Microsoft Windows 10: Is it worth upgrading?

Gabriele is sceptical about Windows 10 and still misses XP. With a new version due in a few days, is it worth taking the free upgrade, and when?

I know you can't answer, but what do you really think about Windows 10?

I was sceptical from the start. When I started reading about how a lot of people in business are going to stick with Windows 7 until it's ended, I thought: Get another machine now while they're still affordable, and did so.
