The problem with your argument Pedro is basically you are saying ‘people should use Surface because it’s cheaper.’

When it comes to new tech like this, I think the most important metric is how fluid the whole experience is. Consider the whole idea of sketching/prototyping historically: debate has raged for decades. You can spend WAY too much time prototyping, then the build is started after the calendar and gas tank have been depleted. The cost difference you talk about here represents about 10 minutes of meeting time on most projects.

I find this compelling also because I think that Developers are going to start stepping up into this space and that’s a great thing. The tools have to be much easier and more fluid, and this is the first one that looks like it might be opening that door (at long last).
