I have begun looking at the Magento E-Commerce Platform / Shopping Cart and I am looking for anyone who has any experience implementing on this platform. I have been investigating this platform as an alternative to one of my stores. If you have implemented on this platform,please let me know.

What do you like about the platform?
What do you dislike about the platform?
On a scale of 1-10 with (1 being horrible, 10 being easy) where would you rank the ease of use?
How long did it take you to implement your store from installation to initial roll out?
Did you roll out one store, or multiple stores?
How easy was it to migrate from another platform? (if applicable)
Did you integrate any 3rd party components or add any custom features above and beyond the standard
installation?
Did you use Community Edition or Enterprise Edition? What was your reasoning?
If you implemented this platform, did you use your own developer staff, outside web design firm, or are you a do it yourselfer?
What advice do you have for someone thinking about implementing on this platform?
Would you recommend this e-commerce platform to others?
Are you affiliated with Magento in any way? (Yes/No)

Thanks for any feedback you can provide.
