They're fun to play with. I've been messing around with mine on my A1200 for the last month, converting digital pics in ImageFX to DCTV format.
While it's fun and nostalgic for a while, I don't think I (personally) would use the DCTV for anything serious these days, as there are much more efficient options out there.
However, if it's all you have, or if you are bound and determined to work to limitations, you can create some amazing stuff on the DCTV.
