At MacWorld I learned about a handful of iPad apps that are great for work. Some have been around awhile, some are new. Here are my top 10 iPad apps for work.

1. GoodReader, $5, reformats PDFs so you can read them more easily on your iPad. Plus you can make annotations. And sync everything via Dropbox.

2. Office2 (Office Squared), $8, allows you to create, view, and edit Word, Excel, and PowerPoint docs right on the iPad. Syncs with Dropbox. QuickOffice, $20, is very similar but costs a little more.

3. OnLive Desktop, free, if you need to work on a Windows PC you can do it using this app. Store up to 2GB of documents free on their servers, so you can access them later.

4. Invoice2go, $10, create invoices on your iPad and send them to clients, plus if you are on Windows you can sync the invoices straight to your Windows PC. A Mac version is said to be coming out later this year.

5. Idea Flight, $10 for the presenter and free for everyone else, allows one person to use his iPad to control the screens of the other iPads in the room. So it’s great for presentations, no projector needed.

6. Agendas, $10, create an interactive meeting agenda that you can share with other iPads on the same network.

7. GoToMeeting and WebEx, both free, these allow you to join a GoToMeeting or WebEx meeting on your iPad—no need to sit in front of your computer. (You can’t host a meeting with these, however.)

8. Air Display, $10, use your iPad screen as a second screen for your Mac. Put your email or your IM on there, so you don’t take up valuable real estate on your main screen.

9. Remote Desktop, $6, allows you to control your Windows Vista or Windows 7 PC from your iPad. (There are other similar apps out there too.)

10. Notability, $1, allows you to take handwritten notes (as well as type onscreen), make drawings, and link audio recordings with your notes. It syncs using Dropbox. Use it with the Adonit Jot pen, $20-$30, which allows for much finer line drawing on the iPad than most of the stylus options out there.
