I know most of us use PDF files, they're everywhere. Quotations, letters, even our flight schedules from our travel agent comes in PDF format. It's always a pain when we're on the road and we can't open these documents with our phones when we're checking in at the airport. We always have to print it out, or break out our laptops to get the details. Here's an alternative to Adobe's PDF Reader:

Foxit Software

Foxit Software creates and publishes an alternative reader for PDF documents. They have support for reading and creating PDF documents and other add-ons. You'll find that they also publish a Windows Mobile version of their PDF reader.

So if your Windows Mobile device doesn't have the Adobe PDF reader, don't fret, get one from Foxit here :

and if you use Outlook a lot, you can get a preview handler that's built by Foxit and a good friend, Tim Heuer at this blog:

it allows you to quickly preview PDF files without having to open it separately.
