This is the perfect size for the Joy...with the ability to print-then-cut, use 8.5"x11" paper and it uses all the same Joy accessories...win, win, win! The size & print-then-cut feature are the main differences between the Joy Xtra and original Joy machine. And, while it is slightly larger, it is still light and portable! This is a perfect machine for new-to-Cricut users, those with small spaces, or even tweens and teens wanting to start in the Cricut world! 
And, while I received the product from Cricut to test ahead of time and for my feedback, I am happy to report that it exceeds all expectations. The Joy Xtra is perfect for the home or on-the-go crafter.
