A:AnswerNo, but the Thunderbolt connection does allow you to control USB devices via the inputs on the back. Unfortunately, there's only one Thunderbolt input so you don't get connected devices on more than one PC.
A:AnswerYes, I have one and have no issues. In fact the included thunderbolt cable plugs right in and powers the MacBook Pro as well. Great monitor with speakers
A:AnswerI wouldn't use the monitor as a hub to power anything. Don't think it's built for that kinda power draw. Just usb storage or lights or something.
