I’m currently researching Server 2008 VPS products available, and stumbled upon bytehouse’s offering:
Why use a Windows operating system?
Windows Hosting is only really needed if you require ASP (Active Server Pages), Access Databases or VBScript.
Why use a Linux operating system?
If you just need to host HTML (Hypertext Markup Language) or PHP Web Pages, then Linux Hosting would be the better and cheaper choice for you. Linux has a proven track record of performance, stability and security within the Web Hosting industry.
Oh, god, I have Linux envy now, thanks!
