...  carrara will always be there, as long as it works in the latest Microsoft windows version ( or mac version) ! 

Even after that, I plan to keep an older machine to run Carrara, as I do now for Adobe PageMaker in WinXP.   great idea, problem is my computers crash and burn after a few years because I buy high powered ones from a cheap supplier :( 

Long ago I bought Dell desktops, but I think their quality has fallen off.  Now I buy Toshiba laptops, and have desktops built by a one man shop here in Houston, all Core i7.  He uses top quality components and of course is available to fix the machine.  And he can fix the laptops, also.  Both have dual hard drives (altho I think Toshiba no longer offers that), with "Casper" backup software that creates a bootable copy of the working hard drive.  Carrara runs fine on both under Win7, so hopefully I can run for a good long while regardless of what MS and/or DAZ do.  And yes, I realize I should not make statements like that ...
