Magento and online store

Yesterday i read something about magento, opensource online store software. I have already known about zen cart, oscommerce, xcart. But this magento is new and quickly picking momentum. Everybody talks about it in opensource store market. I really wish to open a store of mine. I hope to get some improvement in my life by doing so. This would be really new in coimbatore even tamilnadu. Most people started purchasing online and this trend will increase in the future as well. I don't really know what kind of stuff could be sold and how could i procure it. If this business picks up then it would be a turning point in my life. My GOD bless me.
