The biggest difference is that on OZ 'ipkg install <something>' just works, you don't have to spend days to find out what dependencies that package needs.
Well, that's not quite right but anyway, for me main differences are:
- OZ is maintained in a more formal way by more people with a more open and better organization and a thus is more likely to be the distribution that will be here longer (ie if sashz is getting bored by pdaxrom.....)
- OZ provides (both opie and gpe) a uniform and complete desktop environement, while pdaxrom is more a compilation of existing apps and hacks. This requires a LOT of work, but a lot of work has been done on gpe, 3.5.3 was clearly of first port, 3.5.4 is working nicely and it's great to be able to use an application so set the fonts for all the system for instance.
Why do I use pdaxrom then? well pdaxrom was here before oz/gpe, and was arguably working better than the first oz/gpe releases, native and cross compilation was easier to get started with pdaxrom (the nice sdks, it might still be the case for the native sdk you just drop the sdk in the home directory and you're ready to compile)
Will I start to use OZ instead of pdaxrom? I don't know, but I'll be sure to check and try everything that's available and to use the one that suits me (of course as I have more inner knowledge of how pdaxrom works and as it's allready doing what I want, I might not find enough energy to switch)
I think that's great that we have choices and the possibility to try everything for free, just like I like the possibility to try and choose betwenn debian, mandriva, ubuntu, suse, gentoo..you name it..
I know that not everybody has time to try and decide by himself and we just want to know "what's the best" but there is no answer to this question because what we would like to know is "what's the best for me", hopefully with kexec and booting from a card it will more easier to try new things without breaking the previous installs.
