To quote from the Adobe Illustrator CC page:
Create vector art and illustrations using advanced, precise drawing and typography tools. Work quickly and intuitively on everything from brand identities and marketing materials to graphics for the web, video, and film. Illustrator CC is part of Creative Cloud, so you can sync color themes, workspaces, and projects — all with just a few clicks.
There are several things Adobe has done that will make using Illustrator a lot easier:
- The Pencil tool has been rebuilt to help making line segments and curves easier and to give more control.
- Live Corners allows editing and re-editing of corners on both shapes and paths.
- You have access to over 700 fonts from within Illustrator to help create the exact image you want for your designs.
