I had lots of different computers too.  I was a wild man at punching cards!  I spent a long time on Dec Vax minicomputers, and their OS is pretty well the same thing as OS X on a Mac, without all the fancy stuff on top.  The Dec computers are still alive all over the place.  I remember one system I was involved in building had a large room set aside for a 2 GB disk farm!  Now an SD card the size of a fingernail.  I know - we all know these stories.

Some trading packages only want to  run on Windows, so I think whoever posted the idea of having all three OS's on a Mac has a good idea.  You can have them all running at once.  But only Mac OS on the web.  Zero viruses. 

I suppose with KXL the way it is, I could buy a new computer.  But it's too much hassle, and I don't want to count chickens.

All the land buying going on is brilliant.  Whoever is doing their land purchase plan is very good at it.
