I think it's a shame because Darcs has beautiful theory behind it and is written in my favorite programming language. I feel the same way about some hardware, like the SGI Octane with MIPS processors, dual board graphics cards, and a crossbar architecture. Practically speaking it's worthless because it pulls way too much power and even a cheap netbook is 10 times as fast, but it's still my favorite computer. So it's not a shame that there's a better product, it's a shame that the product I want to be the best isn't.
