ESXi installs on the bare metal instead of some other OS - and thus is able to 
do a better job of managing the VMs than something working on top of some other 
OS's drivers.  You don't even use the console except for the initial install and 
some very minor commands - you have to have a windows machine to run the remoete 
console client for the real setup and control work and to get the consoles of 
the guest machines.  However, it isn't necessary to keep the client connected 
all the time and you can arrange direct vnc/ssh/freenx access to the guests once 
the network is up.
