Software
An article by Farhad Manjoo in Salon on the SCO suit against IBM and Linux comes to almost the same conclusion I came to last Thursday - that the suit could end up legitimizing Linux to the mainstream business customer.

Relevant quotes: "...the SCO lawsuit may do more to ratify Linux's ascendant position in the software universe than anything else. Amateurs tend not to create software that inspires billion-dollar lawsuits. SCO's frantic scrambling to salvage something out of its Unix holdings -- with Microsoft's support -- is the clearest sign yet that Linux has arrived...'In the end I think IBM starts indemnifying its customers'...if IBM does do that, it would be quite a win for Linux; all those claims, so often casually mentioned by the likes of Microsoft, of Linux being somehow dangerous for business would be wiped away."
