PixaMSN

PixaMSN is a tiny instant messaging application that comes as a minimal replacement for MSN Messenger, allowing users to chat online on the go.
The program doesn't need to be installed, which means it can be easily copied on a USB Flash drive and accessed from any other Windows workstation without prior installation.
Although it comes as a light alternative to the popular MSN Messenger, PixaMSN provides nothing else besides chat features; this means you can't use your webcam, transfer files, use emoticons or nudges.
Instead, you can send and receive messages to and from your buddies from a very clean interface, while also being able to change status messages.
Other than that, PixaMSN allows you to add a new user to the contact list, change your name, popup on new messages or flash the TaskBar and warn on newly received mail.
As described, it's a very light software solution, so it's absolutely no surprise that it needs only a minimum amount of computer resources to run properly.
Just as expected, there's no help manual included in the application, but beginners should be able to use the program just fine, mostly because it all comes down to just a few features.
Overall, PixaMSN is a nice way to talk to your MSN contacts on the go, and the fact that it doesn't take much space on a flash drive makes it the perfect MSN Messenger replacement wherever you go.
