Just finished testing Server 2008: Start->Shut Down, drop partitions...
BIG, slow copy of Vista, well it has intuitive navigation and organized tools, but again, tools are separated, divided ant split apart (compared XP/2003). I've tested it on 1024ram@3Ghz Intel board. No good. System is running slow, OS is supposed to share HW resources not to eat them herself. Ugly.
Power Shell: hahaaaaaaaaaaaaaaaaaaa- that was my reaction. Ugly copy and a bad one of good-ol shell.
Still looking forward to test Core edition. But not today, maybe tomorrow. Today i'm already angry.
