None of the modern systems have been "consoles" -- heck, the closest thing to a "console" device is the DS, really, as it is the only thing to vaugely contain a "control panel" on the unit and seperate from the main screen.
"Console" comes from the fact that the first home game systems were game consoles -- a small unit with a bank of buttons, controls, and switches. Modern systems don't really resemble a console at all, but some stuffy folks insist on using the term "console" as an attempt to distinguish between game system hooked to an external display and portable systems with a self contained display.
I do think that the gaming public at large would tend to use the word "console" to refer to any gaming platform -- "what console is that game coming to". Let folks use it as they wish... there's really no "wrong" way, as there is really no right way to use it when referring to game systems anymore.
