A little while ago, I came across GiveAway of the Day, a really good website offering a free software package daily. Each GiveAway file offered is available for 24 hours. If you want to download the package, you must also install it and activate it using an activation file inside the package, all within the 24 hour period. Note: If you need to reformat your hard drive, the GiveAway file(s) you've downloaded/installed/activated will no longer be available...but you can always choose to purchase licenses for the packages you like if you want to download them again from the home pages of each product.

This software is not "trial" versions or crippled in any way, assuming it is activated within the 24 hour period in which it is available. And, new software is available each day. This is a site I bookmarked almost immediately, and one I visit on a daily basis.
No, I haven't downloaded every available package...but the ones I have downloaded are useful and of excellent quality. The software is of various types: Screensavers, organizers (such as for notes and personal information or mp3 collections) and more. Well worth checking out.
