Can anyone point me at very specific details of what the limitations of the Web Edition of Windows Server 2008 are? I have seen the higher level comparisson charts of the various editions but no detailed specifics.
I understand they removed the inability to install SQL Server and significantly raised the RAM and CPU limits. But a little googling indicates that in Server 2003 the Web Edition has a limit of 10 inbound UNC connections to keep people from using it as a file server. Does this limit still exist in Server 2008? Are there other limits?
In addition to the comparison pages on the Microsoft website, be sure to check the Licensing page.
From http://www.microsoft.com/windowsserver2008/en/us/editions-overview.aspx
There are some really good pages under the "editions" link at the top of that page as well. Specifically http://www.microsoft.com/windowsserver2008/en/us/compare-roles.aspx states that the Web edition does NOT support File Services.
Following on from the answers above (the pdf isn't that easy to see on the pages).
Here is a direct link to a PDF overview on Microsoft's site of each server role (feature set) available in each edition.

We are running a Server 2008 Web Edition with SQL server 2008 on it.

You cannot use the Web Edition to be a Domain Controller, Terminal Server, Hyper-V host, etc. It is a Web Server only.
According to Microsoft the main difference is that the "web edition" includes Microsoft's own web server (IIS). More differences can be seen on the following page:
