Ubuntu derivatives offering a more complete OS: Pinguy & Zorin
One thing I dislike about Ubuntu is that the installation process involves downloading 300-400 mb of data and it doesn't end there! Even after installation, the first update is about 200 mb! Further, to install your favorite programs, you have to download another 100 mb!
What if the OS itself gives you most of your favorite programs? That would save you a lot of time and internet data indeed.
