I've been collecting classic Macs for the past 16 years, ever since one of my teachers gave me a Macintosh SE and a Performa 6220. Every now and then I boot one of my classic Macs and open up ClarisWorks. One of the things I like about most software written for the classic Mac OS is their strict adherence to the Apple Macintosh Human Interface Guidelines.
Maybe it's just the nostalgia talking, but Apple Pages and Apple Numbers do not spark the same joy in me that ClarisWorks did, though Apple Keynote is a superb software product. I've tried using Apple Pages and Apple Numbers in the past, and I often end up resorting to LibreOffice, despite the fact that LibreOffice's interface isn't Mac-like while Pages and Numbers are first-party programs. It's hard for me to articulate this objectively, but Pages and Numbers seem to deviate from the traditional UI for word processors and spreadsheets, respectively, and I'm just more comfortable with more traditional word processors like ClarisWorks/AbiWord/Microsoft Word/LibreOffice Writer and traditional spreadsheets like Microsoft Excel/Gnumeric/LibreOffice Calc. I've tried Pages and Numbers, but I find myself reaching for LibreOffice.
Perhaps it would be nice if somebody created a modern-day ClarisWorks as a type of counter-weight to Microsoft Office and LibreOffice.
