I'm most happy using LMDE. I'm using LMDE pointing to squeeze not testing as I wanted a more stable laptop. It is so much better than Ubuntu. No annoying issues, no hangups and restarts. Very pleasant to use. There are a few things I would like to know.
1. I have added the squeeze-backports to list of sources. But the apps in backports do not show up in software manager. I need to specifically go to debian's site, check if a more recent update is available in backports (compared to stable) and install it from command line. I understand, that it is to ensure that people do not pull too much from backports as it can be unstable. But I'm willing to take that risk. Is there to make software manager show backports too? Else is there any other way to see packages available in backports?
2. Since I have set to debian squeeze, I expect I would be a little outdated in core packages. But the mint development would be based on the debian testing release and hence using more recent packages. Would I face any issues while updating mint packages because of this?
3. How stable is debian testing? I'm a little afraid to use the testing release as I use my laptop for development.
