You're right about the kids today being a lot more tech savvy, and with a comfort zone surrounding all things computerized. Still, this will be her sewing machine. I really think you need to know more about what she wants to do with it, and then help her make a good choice. Once you know her intentions, you can line up several machines for her to look at and try out. Would any of us buy a machine without giving it a test drive? Especially when it's so important that she like it and is comfortable with it? I wouldn't make the decision for her. Take her around and let her try out several machines, and let her decide what she's comfortable working on. The best thing you can do to help ensure success here is to involve her in the decision making process.
Anyway, that's my 2¢ worth.
Cheers!
