Tonight I activated SBS 08 & did a few Server 2008 tweaks from Grav!ty's thread, I couldn't get the sidebar going tho
Here are a few more screenshots of what is included in the Standard Edition.

*I suppose I should add that there are a few bugs in this build & on this (under RAMed) test rig w/ 2 GB of DDR2 RAM it still takes 5 minutes for the OS, after restarting, to stop the Services & 11 minutes to hit the desktop!
