I finally decided to go with Virb.com for my portfolio.
Honestly one of the main reasons why I decided to go with them was because they have easy password protection which allows me to keep my portfolio private.
I really think that having an online portfolio is the best way to go. Always accessible and definitely easier to update and maintain. Plus if you ever go on an interview no one notices that your carrying your book.
Im sure I may get some stares from people who are used to actual hard copies of their book but Its definitely the way of the future.
