works great with virtualbox. Now still need to learn the tricks. where is notepad, where is the run command, etc. Do not install Office 2010 it will hand the machine and now you will have to troubleshoot. I am still trying networking works great. Could not find the command prompt but manually browsed to the c:\windows\system32\cmd.exe and got to the command prompt. It actually runs some apps which were written in 1995-96 to work only on DOS.
In the keynote, they showed that just typing 'cmd' from the Metro screen takes you to search and finds cmd.exe on the disk. Probably the same for notepad.
