If I may add a respectful disagreement. I run dual o/s on my lappy through a partitioned drive - Ubuntu 8.10 and Windows xp. It's a great way approach as I do agree that not all windows apps work well through Wine. Depending upon what I am doing at a particular time, I'll just boot in/out of one o/s to another.
I do have to say that Windows avi burning/converting apps are more plentiful, and work far better, than the variety of ones I tried in Linux. I have encountered many times an avi that will not convert/burn in a Linux app only to have 100% success when I try it in some of my Windows apps; but that's a minor issue. The benefits of Linux far outweight Windows only within my personal opionion. Others will differ but that is not the point of this thread.
I do want to comment briefly though on Deluge. I tried using Deluge for a bit, but reverted back to uTorrent/wine. I'm not particularly satisfied as I find uTorrent affords far more information and ability to tinker with upload/download speeds/settings, bandwidth management, peer data and user preferences. Deluge works - if what you want is a basic torrent client, but since I require more user flexibility, I go back to uTorrent.
my two cents anyway....
