Agreed. Many of the features on this page are either biased towards PowerShell, or so oddly defined as to be nonsensical. For example, in the `Programming Features' section, Bash is listed as being unable to do Arithmetic  and yet echo $[2+2] (a shell builtin) returns 4. Admittedly it's only integer arithmetic, but still. I have no idea why this is missing. Likewise, in the comparison of features section, Syntax highlighting is listed as being "no" for everything except PowerShell "(In ISE)". This is like writing "Yes (In Vim)" by Bash, or anything else you care to mention. It's also the case that one can define syntax highlight quite easily in most of the UNIX shells, if desired. It's just not enabled by default at the prompt. This article needs attention.
