I found two interesting articles / post.
First one is written by Paul Graham – Microsoft is dead:
A few days ago I suddenly realized Microsoft was dead. I was talking to a young startup founder about how Google was different from Yahoo. I said that Yahoo had been warped from the start by their fear of Microsoft. That was why they’d positioned themselves as a “media company” instead of a technology company.
Factors responsible for M$ death…
c) Broadband Internet
d) Apple Mac OS X
Other post is written by E@zyVG:
If you run Linux and install free software, you wonâ€™t have to worry about this ever again! Most of free (as in free speech) software is free (as in free beer). You can find a free replacement for most of the commercial software out there. They might lack some of the advanced functionality, but theyâ€™ll be more than enough for most people….
Overall it is an excellent list of some commercial software, and their open source equivalents.
