Hi, Thanks for your answers. I think also that starting simple and small is a way to increase the use of Sage also. My questions about interface and language because I'm trying to use CAS in education with notebooks with a textual oriented interface instead of notebooks with a calculation oriented one. This is because I want to emphasize problem solving using the heuristics of George Polya, so textual description of the students interpretation of the problem is more important that calculations. In this regard the notebook web interface has some issues and the integration of tinyMCE is a good step on user friendliness but there is a escape of the WYSIWYG metaphor to LaTeX code when there is a need to write math (and of course in a problem solving oriented math course is supposed to pass a lot). A work around that I'm using is the TeXmacs interface for Sage, but then I lose all the nice collaborative and ubiquitous features of the sage web interface. Having a nice equation editor integrated with tinyMCE (may be made in something similar to 280slides) would be a good step towards a textual oriented interface. Of course you're thinking supercalculator integrated in a small form factor laptop, but also you're thinking about filling the gaps so knowing your thoughts about the gap between textual oriented and calculation oriented interface would be a nice thing, even if this is not planed for mathrider.
