IT Comparison  - 100% independent Comparisons (Overview)

Did you know that almost 90% of all products comparisons on the Internet today are either written by the product vendor, funded by product vendor(like HP, IBM, Dell, VMware, Xen, Microsoft), or aimed at selling that vendor products. Only few honest comparisons exist on the web today focusing on educating IT Professionals. That's where the idea of came from. None of our comparisons are funded neither motivated by any vendor. We reference vendors comparisons in our charts only after evaluating the competing vendors comparison and make sure they can stand for their claims. This site is created with the aim of helping IT professional in saving valuable time, resources, and money comparing products. We offer many IT Comparisons and  VS related to many IT products and solutions.
