Apple's spreadsheet app is great for tweaking your data on the go, but on the Mac -- while it's improved -- it still doesn't have all the features of iWork '09.
When you first launch Numbers, you're greeted with all your saved spreadsheets. You can pick up where you left off on another device, or create a new spreadsheet.
To spice up your data you can create 3D charts and choose from several different layouts and colors. Once you insert 3D graphs into your spreadsheet, you can rotate them with a swipe of your finger.
When you want to team up and work on something together, you can hit the Share button in the upper right, and share a link to your spreadsheet via iCloud.
If you don't like how a graph or table looks, you can touch the object, then touch the paintbrush button at the top and select a different style.
The new version of Numbers for iOS has almost twice as many templates as the old version. The templates are organized into categories so you can choose the right one for the job at hand.
