Adium is already a popular instant messaging application for Mac offering as it does access to multiple protocols and accounts. You can use it to connect to AIM, MSN, Yahoo!
, Google Talk, Jabber and other chat services all at the same time, meaning you only need one chat program open for all your different accounts.
In this special mobile bundle, the application is designed to be placed on your portable device (e. g. USB key, iPod, portable hard disk etc) so that you can run it on any Mac you like.
Simply connect your portable device and run the program directly from it: all your profile and account info are stored on your device, meaning there's no need to set-up your client on each new machine you use.
The design, implementation and performance of this version of Adium are just as great as on the normal version. The only thing I'd question is just how useful the portable version would be: between work and home it could serve as handy but with very few internet cafés opting for Macs, it might prove less useful for travellers and students.
