Comparison of computer algebra systems

(Find sources: Google (books · news · scholar · free images · WP refs) · FENS · JSTOR · TWL)

This article has multiple issues:

It is pure WP:OR: Although there are published papers that compare some computer algebra systems, none is cited and the content of the article is not based of existing sources.
Several of the cited softwares have nothing to do with computer algebra. "Computer algebra" implies the ability of doing some algebra on a computer. This excludes formula editors and software making only numerical floating point computation.
Several of the cited software are experimental software, that have not been published nor cited in scientific publications, and therefore do not satisfy the General notability guideline.
The article does makes any hierarchy between the systems, presenting at the same level widely used systems and confidential software (fringe software). Therefore the article does not satisfy the policy WP:NPOV.

It is not possible to rewrite this article for satisfying WP policies because of the lack of convenient sources. The only possibility that I see is to replace this article by sections in computer algebra systems, presenting the main computer algebra systems (with {{main}} template), explaining why there are important and summarizing their main abilities..

keep I was surprised to see this article up for deletion, as I found it a useful CAS survey for an academic project two months ago. Regarding the issues raised,
The main content of that article is a set of tables summarizing CAS software package properties and capabilities. If summarizing other sources is original research, then all of Wikipedia is original research.
