It's more than I pay for IDEA Ultimate.

From the absurdly CPU-intensive landing page it seems the novelty is mainly some network storage and an LLM-integration, things I already have several of in my terminals on my work computer. I switch over to them in the blink of an eye because my window manager is extremely responsive and keeping their output localised and not split up in a single pseudo-conversation in my current main terminal is a perk, not a bug.
