Ease of install is part of the same pattern. PHP has always been easy (with connections to a free database), and got easier with good package management systems. What's coldfusion like for ease of install, ease of install with database access?

ASP for Windows was huge. It was even easier to get started on than PHP because you just needed to install IIS from a EXE and you could reference access files. The only reason it's not still massive is that MS moved on.
