Sure, Ubuntu is very powerful and safe, but it is still missingquite a few of the features that make Windows so popular and easy to use. I am not bashing Ubuntu (or Linux overall), just stating the facts as I see them. I am (this far) happy with Ubuntu on my computer, it start faster than Windows (much faster than the almost1 year old installation I had running until Friday), and have the equivialent to many of the programs I use on a daily basis.
Update: This entry somehow got corrupted. Thanks to Chris Whisonant, he helped me by deleting it last night so I could restore it this morning. Sorry if you tried to read it while it was missing.
