This is a little like asking "I'm drinking Sauternes and I like it a lot - should I look at Burgundy?"
If you are not willing to do your homework (i.e., the evaluation of the pros and cons of these two systems for your own development and deployment scenario) yourself, the answers you'll get on either list for your question won't be able to help you much because the list of salient evaluation criteria is long, and a serious assessment requires intimate knowledge of your situation. >From a technician's point of view I'd say that it never hurts to look at another system to widen your horizon. The only risk I can see is that it might make you yearn for a system that has all of the goodies. ;-) -W On 2 January 2011 00:01, dc tech <dctech1...@gmail.com> wrote: > Thank's Edson.
