It still amazes me how much people short change their own intelligence, or that of their loved ones. The entire concept of Metro is to make windows easier to use, but at the same time MS did not want to throw out the usefulness of hundreds of thousands of legacy programs. But by trying to out ipad the ipad with Windows RT MS lost big time, it's not worth doing.
I've never felt that a windows tablet was too "hard" or "complex" for me to use if I wanted to stay within the Metro ecosystem. I understand the app market is not there yet, but it has tremendously grown in the past year and most of the big apps are there and eventually it will catch up.
For me, with a windows tablet, I have a "dumb" tablet similar to the ipad AND I have a full computer, I can run it as either or both, but don't have to limit myself to only having the dumb tablet. It's all about choices, but sometimes it's about NOT having to make that choice and having your cake and eating it too.

Don't forget the HIGH cost of data, do any of us truly have the luxury to move even a 1gb file onto our computer over cellular data? What about those times when we don't have data access/cell reception? Not all of us sit at home in our wifi umbrella, I don't have wifi at work or on the road when I travel.
Some may call things like a memory card or USB as archaic, but I find them INCREDIBLY useful from day to day. And I still have the cloud I can use in addition to those things. Why people consider hamstringing themselves progressing I'll never know.
