An interesting paper in somewhat the opposite direction, but still building on Landauer's work is "Ultimate physical limits to computation":

The end of the abstract:

> [...] quantitative bounds are put to the computational power of an `ultimate laptop' with a mass of one kilogram confined to a volume of one liter.

That along with "on the computational capacity of the universe" was the paper that stopped me from ever taking Seth Loyd seriously again. Later finding out he was a creepy Epstein croney... well sometimes the universe makes a lot of sense.
