Scott, thanks for the best laugh of the day!
You could almost label this review, "Part I." There are some categories of software — text editors is one, image editors/viewers and archiving apps being others — that there are so many products to review that it's easy to get lost in the alphabet soup of programs. Mouser, I liked how you explained little details, e.g., novices might not understand exactly what a project is or what code folding is, but you provide descriptions throughout. Starting and finishing with UltraEdit, and then comparing features against it is a sound approach. If users take the time to go through the list of apps and download a few to evaluate for themselves, they'll quickly see their shortcomings vis-a-vis UltraEdit. Differentiating between what makes a good general text editor and programmer's editor is key to this review. Some misguided critiques arise solely out of either confusing the two or conflating them. For example, someone like me would disappointed with Zeus or PSPad as a text editor, but someone who codes would likely be delighted.
Even the developer of Zeus admits that his is a programmer's editor and is not suitable for large files. It's courteous that he shares that up front, I believe. Like a lot of writers, I use a text editor to compose an article, monograph, or even book, so I need actual, practical "text" features more than coding. (I take the raw text and "drop it" into whatever container program the publisher wants, such as MS Word, InDesign, Quark, etc.) I do basic HTML/XML, and small bits of PHP with my text editor, so choices like UltraEdit, EmEditor, and EditPlus are good for me. But I'm not writing any variant of C code, and thus have no use for VIM, Emacs, SlickEdit, etc. As you say, that's a different category, much like the difference between a word processor and a desktop publishing program.
Next year, IDM will release its UEStudio IDE (Integrated Development Environment), and since UltraEdit will be the backbone of UEStudio, they will be upgraded in sync. That would be a good time to revisit this category, if not sooner.
