Yes Desktop Manager is what I was referring to. It is very nice.
And yes the two delete keys are weird also the lack of a numlock key.
Also on he two finger thing I will probably get used to it. But when I am home I attach a two button mouse. At work I use XP so the only time I use the trackpad is when I go mobile, usually at school.
One thing I've noticed is that Mac users seem to be more on the power user side. If they find a hole in the system they will find a way to work around it whereas Windows users just accept how Windows works at face value. There seem to be alot of shell enhancement type apps for the Mac and it appears as though many times their features get rolled into the system. It's actually pretty cool. Sort of like the OS can learn how we work and adapt to us rather than us adapt to it.
My numlock key is F6 - you should have one too somewhere.
