Ubuntu Software Center to offer install-free application test drives
Find a program you'd like to try out -- but don't necessarily want to install just yet -- and click the test drive button. With the qtnx package installed and your Internet connection at the ready, the program will "buffer" and then launch, giving you an install-free look at what it can do.
Check the video after the break to see Software Center test drives of AbiWord and Chromium in action -- it really is quite slick. This feature, incidentally, will make its debut in Ubuntu 11.04, which is due to be released next month.
