Ubuntu does not know what it wants to be when it grows up… The seamless mode of VirtualBox makes Outlook 2007 into a “worthy windowed” application and saves me a bunch of time running various Operating Systems needed for work and play.
Since I still use Outlook 2007 for a fair bit of planning and execution of my projects, the use of Virtualbox 2.1 in Ubuntu 8.10 makes all the difference to having a working tool user environment. Its all about tools folks.
