If you go back in time, and I mean WAY back to OD&D, the notation for dice was a helluva lot more confusing. You saw things like 5-20, which could be generated a number of different ways, without any notation at all. So if you are nostalgic for D&D notation, remember that the xdy notation was a simplification of notation that didn't really begin to take precedence until late AD&D and 3rd edition.
But for the record, I like the xdy notation since it tells me exactly what my odds are. 6d4 and 4d6 may generate a similar range of numbers but they do so very differently and tell a much different story from 6-24 and 4-24.
