Back in the day, you could:
* Be bold enough to use Linux or FreeBSD and use CGI or Perl as the only free version
* Use ASP but pay license fees for Windows NT, ISS and SQL Server
* Use ColdFusion which was kind of trendy but was pretty expensive.
When PHP arrived it was so refreshing. I used to make my stuff in Apache+PHP, MySQL and Linux and it was magical what you could do with very few lines of code.
The worse part was to manually get the sources of the dependencies one by one, hit ./configure and make, so you can compile a php module for Apache
In those days Microsoft was pretty strong, everything used to be closed source and payed and that's why for people who understand what it was back then, this does not sound like the splashy announcements of today.
That's why every time you see Linus, Stallman or any person that was active in the open source movement, you should pay a beer to them. The world of technology owe a lot to them, specially the underdogs.
