With three separate computers, it takes a lot for a piece of software to make it onto all three. Software that makes it easier to install on all three or keep all three in sync definitely get bonus points. Here are the ones that have recently passed the grade:

• Google Pack: I burned a DVD every year to install a bunch of software on my dad's computer while I'm there for Christmas. It turns out that nearly everything I usually include is on the Google Pack: Google Earth, Picasa, Google Desktop, Acrobat Reader, Ad-Aware, and Firefox. It can even install Trillian. Best feature: one program to install them all, one program to find them, one program to bring them all and in oldness to update them. Worst feature: Norton Antivirus only comes with a six-month subscription.
• Folder Size: Adds a column to show you how large a folder is in Windows Explorer. It's a simple program to win that game of, "Why Am I Out of Diskspace?"
• Foxmarks: it's a buggy beta, but it's something I need. del.icio.us holds on to most of my bookmarks, but I still have quite a few bookmarks I need to keep inside my browser. The 'synchronization' feature ends up putting a lot of empty separators in my bookmark folders, but these can easily be deleted.
• Foldershare: It lets me keep a folders synchronized between multiple computers. I find placing files in a folder the simplest metaphor for sharing between two computers and it requires the least effort to maintain.
