The Core Pocket Media Player (TCPMP) is a replacement for Windows Media Player for your phone. It’s much less bulky than Windows Media player and has a lot more options for controlling how your media is played back. Make sure to download and install all of the plugins for it so it can play nearly and media type. Then once it’s up and running, go to options and file types and make sure its set up to play all file types as well.

Google’s popular Maps service is also available for your phone. Point your phone’s browser at http://m.google.com/maps and you’ll get the download that’s right for your phone. The app is GPS enabled so you can search nearby, or use it for turn-by-turn directions. They’ve also integrated satellite view, street view and traffic. I’ve noticed that the traffic is usually quite accurate, as in when I’m at a dead stop, the road I’m on is also red. I’ll usually take a look at it before my commute home to help decide which route to take.

Notepad++ is a replacement for Windows’ built in notepad. It supports multiple tabs and syntax highlighting for nearly any language. When it installs, it also adds an entry to the right-click menu for any file that reads “Send to Notepad++.” This is very useful for those of us who do a lot of programming and don’t have all of the file extensions set up yet, or those nosy people who like to see what makes their applications tick.

Make your own PDFs with PDF Creator. Like the full blown Adobe Acrobat, what you’d typically need to use to create PDFs, PDF Creator installs itself as a printer, so it works with any application. When you want to create a PDF simply press print, and then choose PDF creator as your printer. Once you click print a pop up will guide you through the process of adding a title and author to your PDF and then ask you where to save it.
I find it especially useful as a print preview function for applications that don’t have it. Or in Firefox when I want to preview how a selected section of of a web page will print.
