Tryton vs OpenERP: From internet Part 1

If you are going for the other direction (other than Django)I would really recommend tryton and keep the hell away of openerp. Tryton is really open source. openerp is just like compiere, openbenbravo and many others: "Was truly open source" than, came the money!!
We made the change a while ago. I took a lot of work. Spare yourself this trouble. Go Tryton!
