I saw Taim ask about ROMs in the other post to the Pittsburgh ZUG. Just thought I might be able to shed some light with my experiences.
The major ROMs to consider are OpenZaurus, Sharp, TKC, Cacko/Crow.
I love the OpenZaurus rom. It has some sweet features (such as the battery monitor actually being accurate, good configuration options, etc). I normally use it with the 64-0 configuration, in which you don\'t have a ramdisk, and instead can make it so your filesystem is spread between Flash and SD card. The biggest problem though is that such a configuration is quite slow, and OZ is very unstable when it comes to different CF cards. It tends to freeze for thirty seconds or more when I try to swap cards, or turn it on with some cards. For that reason I really don\'t use it anymore, although things like Kismet and Wellenreiter seem to work better on it.
The Sharp rom is, well, standard. So there isn\'t much to say about it.
The Cacko/Crow roms have some real potential, but I have had problems installing them.
My favorite rom right now is the TKC rom. I\'d really suggest it if you aren\'t on OZ. It is very stable, has some nice features such as a very good looking interface and preinstallation of SubApplet. I think it will continue to be extended as well, as they appear to be supporting the person who originally did the mod for them.
I\'d be curious to know if anyone else in the Pittsburgh ZUG have tried other roms and what they think...
