I don't have the Craft Robo, but do have the Wishblade. (Craft Robo, Xyron Wishblade & QK Silhouette are all the same machine, but branded and distributed by different companies.)
It is really cool and I have used it a ton for titles - using all my cool computer alphas and TTFs. Honestly though, it is a huge learning curve if you want to go beyond titles. Esp if you want to do Disney stuff. There are a lot of pre-made templates out there that you can buy or even download for free (for personal use), but they are not Disney due to the copyright. You can make Disney ones, but can't distribute.
I ended up getting a cricut for cheap from a friend (when she upgraded to the expression - she is NOT computer savvy at all!). I only bought the Disney carts to make it easiest on myself. I wouldn't trade my Wishblade for a cricut though - I just have too many fonts to not use them in my layouts!
