Can I or how do I revert back to iWork 09 on my iPad? **DESPERATELY SEEKING HELP**

The only way you can "revert" is if you have the older version in iTunes on your computer (meaning you haven't downloaded the newer version). Delete the app from your iPad, sync it to itunes and ionstall the old version from there.

"a laptop that with MS/Vista OS that I rarely use and don't even know if iWork Pages is on it."

No, it does not. The iWork suite is exclusively for Apple devices, there is no native Windows version. There never will be.

The newest version of iWork supports a web-based version that works quite well in a browser on any newer computer, Mac or Windows:

If you use the new version of Pages, you can work on both the web version (on your Windows computer) as well as the iPad version - the documents can automatically sync over iCloud. This is not possible with the older version of Pages.

As James stated IF you have synced or backed up your ipad to your computer at some point, it should have the old app on it.

Here is a previous post about getting it back on your device.
