Can you install iWork '09 on multiple computers?

[travod]

Title. I got iWork '09 (the disc) when it came out and used it for my laptop, but I plan to buy the new Air this summer. Can I reuse the disc? I can't find the answer online.

And does the new Air still have that feature where it can read a disc from a desktop computer?

Why not? It's your Mac. You may install it on all the Macs you own. You can do CD/DVD sharing to other Macs. You can also make a disc image of your CD-ROM and simply use that; put it on a HD or USB stick.
