I rarely touch my iPad or Android tablets since I bought the Surface. It nicely meets my needs for every day use. Once in a while I will fire up the laptop (running Win 8 Pro) for a task which I can't quite do on the Surface but I find that doesn't even happen often these days.
But then, the bulk of what I need to do is email, web browser, watching movies, and printing out work related documents. All of that is easily done from the Surface. I don't think the Surface RT was ever meant to be a laptop replacement, just a much better mobile device, and it does that very well.
I personally find the Surface to be perfect for what it was designed to be.
