okay i read like one paragraph on the windows site and it looks like it is server client type software. Where the old pc turns into a terminal that will connect to a server will all the windows xp stuff. I dont think it is something we will be using here. Unless someone wants to put a slow computer for every seat in the car and have one main super server to manage it all.
edit: quote from microsoft
Windows Fundamentals for Legacy PCs is not a general-purpose operating system. It is designed to work with the Microsoft Remote Desktop Connection client or third-party clients, such as Citrix ICA. In addition, it allows for a limited number of workloads to be executed locally, including security software, management software, terminal emulation software, document viewers, and the .NET Framework.
Maybe it can run local programs too but more or less designed for terminal type aplications.
