I like that it's very easy to use, especially for beginners who have no experience with creating graphics or vector images! The software has great tutorials which are really helpful when learning how everything works together as well as giving tips about using certain tools more effectively than others.
It also makes sharing files between multiple people so much easier since you can send them just one file instead of having every person open his own copy (which would be difficult if they were not working off from your computer). Sometimes there will come up an error message but nothing major happens - maybe try restarting? As far as price goes, while this program isn't cheap compared to other programs out their such as Adobe Illustrator etc., its value does make itself worth paying because at least we know what our purchase gets us versus something cheaper without knowing exactly whats included/what features work best with ours needs /etc..
