I currently have a dell Inspiron 580 with intel i3. I had this computer since 2010 or 2011. This desktop is slow now and make too much noise. I been wanting to make the switch from windows to apple. Do any one recommend to change from a windows to a apple? I have been waiting 2 month for the new iMac that as everyone knows will not be updated any time soon. I was planning on getting the iMac 27 inch the base model. Should I wait for the new iMac or get this one? Is the base computer good enough? I need opinions.
