Is it? It doesn't sound outragous to me, given that they provide you with however much power you need, ans also networking and people to maintain the facility.

I asked ChatGPT to estimate how much darwing 15W continuously in Amsterdam would cost you per month, and it came up with a range of 2.58€-3.41€ per month. So that's potentially more than half of their fee.

If your laptop is particularly power efficient, you'd also be subsidizing higher-powered laptops. As far as I see there's nothing preventing you from sending a 400W gaming laptop and mining crypto or running an LLM agent 24/7.
