Damn Small Linux is a very interesting project and it brings an entirely new way to use Linux. If you're always on the move DSL is made for you, may it be in your USB key, as an embedded operating system running under Linux or Windows, or even as a business card Live CD that you carry around within your wallet. The concept is great, it's all about mobility and it works very well. Then come the problems. The default DSL has a poor selection of software, an ugly design and lack good configuration tools. But it's configurable. If you give it a bit of time you can learn how to remaster the CD and use the MyDSL extensions. Then you could potentially make it a really nice distribution, maybe a little bit bigger than the original, but still very interesting.
