Best thing about Windows Mobile devices is available third-party applications and lots of free ones. I used to like Palm devices ages ago, it had fantastic third-party apps support. Here is my list of applications which I use it currently, it’s all freebies. 
Click on the header to download the application. (you can download straight from your mobile browser).
1. My Mobiler
View your mobile screen and control with your keyboard and mouse on your desktop.
Obviously you have to connect your Windows Mobile device via USB or Bluetooth to your computer. ActiveSync should be able to see your device.
Great feature I like you can copy and paste between Mobile and your computer.
Don’t be surprise if your mouse is disappears when this application is running. Answer is your move is moved to PocketPC device screen like if you have second monitor.
2. PointUI
This is new refreshing finger-friendly user interface for Windows Mobile (PocketPC) devices. It’s getting better in every version revision.
I use this UI time to time. I started to like the latest version with the improvements.
3. Flash Player (watch YouTube videos & more)
Who wants to watch YouTube videos on your Windows Mobile? Adobe provides Flash Player for PocketPC (link above), But I like TCPMP with FlashPlugIn and YouTubePlay.
TCPMP plays multiple video and audio formats. It’s very good player to watch full length videos as well as flash content. You need to download the following two programs and install them in order.
1. TCPMP program
2. TCPMP Plugin for Flash Video
YouTube Play is another interesting application. You can search YouTube videos from this application and play the flash content full screen.
4. ClearTemp
ClearTemp is an application for you to free up memory on your device. It allows you to clear temporary/unused files and unused registry keys/values on your system easily. It also allows you to clear your Recent Program List, Internet Address History and boot count. You can even change the location of the temporary folders (Cache, History & Cookies) or e-mail attachment folder to the Storage Card.
5. S2U2 (Slide to Unlock)
S2U2 is a simple lock/unlock application which has the iPhone style slide unlocking. It can be used as a screensaver while you don’t use your device. And it’s has a CallerID function.
You can customize the S2U2 look and feel. Check here: Customize S2U2 Battery Animation, Slider Button, Animation & Curtain
6. Network Folder Plug-in
This is a File Explorer plugin to help you map a network drive. You can see the shared folders from Windows machine via WiFi connection. I use it time to time to copy files back and forth.
7. Live Search for Windows Mobile
Live Search name confuses me. This program named "Live Search", but it doesn’t do the web search. It’s a mapping and "Yellow Page" like local business finding program. Those damned "Microsoft Marketing" hot heads. If most people hates Microsoft, major reason is their marketing department.
I like Live Search on my mobile which gives me nice maps including the satellite maps. It’s not frequently updated like Google maps, but it’s very useful. The extra features like "Movie finding", "finding cheap Gas", Voice command, etc., are very very useful at times. You can browse and zoom the map without stylus.
I will add more applications here very soon.
