I guess, but they could hit the mark for both types of customers by adding a removable cage or tray at the bottom that you could just lift out with the press.

Put a metal filter on a pole like a normal press, then slide a second filter over it attached to a holo pole that acts kind of like a sandwich for the grind.

Have some sort of twist mechanism that allows you to lock the 2 poles and lift both together and BAM! quality insulated French press coffee.

Maybe I should drop a patent on this...

It looks like stainless steel double insulation French presses are becoming a common thing, just had a google.

The one thing I can't figure out is why it's not common to have a way to remove the grounds but keep the liquid in the press to take advantage of that insulation.
