In order to shave some of the cost of my next build I am considering going with Vista Home Premium 64 bit instead of Ultimate. The difference is about $77 right now. However, after I build my new machine I would like to setup a Windows Home Server with my current computer. I am just wondering if I will lose any function compared to if I stuck with Ultimate? I know you can't RDP into Vista Home Premium but I read that you can still RDP out. Is this true? I just want to be able to control my home server without the loss of any function.
