We are not technically allowed MSN but they don't block it. Laptop users here have a lot more freedom to install stuff on their own PCs than desktop users do.
I use MS Office stuff, IE a lot as our corporate web and intranet both use browser-based CMS, useful little freeware apps like Windowsizer and Puretext, Novell Groupwise for corporate email and diary, MS Publisher, Adobe Photoshop and Acrobat when I need to be creative.
