What I'm thinking about OsCommerce

Actually I think that there are nothing to discuss. Please read the article about [[articles:about-magento|Magento]. I think that the OsCommerce is worse by every parameter and there are only 2 reasons to use it.

In all of the other cases it is better to prefer the Magento cart. It is more powerful and have got the better structure. I don't believe that there will be any future releases of OsCommerce.
