Hey I'm looking at making the switch from a Dell Desktop to a refurb 2011 iMAC. I would like to know if the 2011 iMAC is a good choice or should I wait? I have an IPAD2, IPAD 3,4s, Iphone 5, 4 Ipods and apple TV. I have 2 laptops that i can use for work. How long will it take to get adjusted if I do go with iMAC?
