You already have the code for adding new inputs, because you fire it 
when you press Enter after entering a single address. As for the rest:

var addresses = textbox.split(/[:,]\s*/);

This is what scrollbars are for. A web page is not a physical device. If 
you think the user will get tired scrolling past the 150 addresses they 
just added, put the address list into a <div style=overflow:scroll> with 
a height of approximately 10x the height of a text box.

And a lot harder to find a particular one and delete it.

I don't think it's as easy to use or edit, and it makes it harder for 
the browser to do things like automatic address completion from a dropdown.

Not all the work. They have <input type="email"> as a building block. 
But yes - webmail implementations are free to come up with their own 
excellent ideas about the best way to handle 150 email addresses in the 
UI. I'd call that a feature, not a bug.
