Dave / Venda,
Thank you for your reply. "De gustibus non disputandum"
If you do wish to make the small effort for seeing the reasons for other people's preferences, reasons that you say you can't see, here I offer you mine.
I rarely play o.t.b. When I do play on a solid board with my kids, I play side by side with them, while they play white and I play black. But much more often I either play on the web or I study chess positions, which both in books and on the web are always represented with the standard visual (a1 bottom left).
Many people (like you) don't mind reversing the coordinates when they play black, and of course I understand them. Many other people (like me) prefer to stick with one fixed frame (a1 bottom left), and this is why many chess sites offer this possibility. If this site doesn't offer it, too bad
