I just order a new 15" rMBP, so I will be receiving it next week. I currently already have two external monitors that I want to connect to it. They have VGA connections. What is the best way to connect both displays to my macbook (aka, what accessories should I get)? Also, it has been a while since I had a macbook. What is the best way to go about charging? Is it best to leave plugged in all the time? or charge until 100% and unplug? Thanks in advance.
