The title of this program might be a bit misleading - Vista for PDA doesn't actually replace the Windows Mobile operating system with Vista, it merely makes it look a bit like it.
Vista for PDA adds a new background wallpaper to your Pocket PC featuring those famous swirly blue and green lines in front of a black backdrop. The text on the Today screen is changed to a gray color, which is perfectly readable.
Thankfully, Vista for PDA uses a background color on the Start menu, rather than a transparent box, making the icons and text easily visible. The theme also alters the colors of the top and bottom status bars in Windows Mobile, adding a rich royal blue/purple hue.
Although Vista for PDA won't add any Vista-style functionality to your device, it does make for a striking theme for fans of the Windows OS.
