It's probably worth mentioning that anyone who wants to try FM11 or TCS4 can download it and do so. It's a fully featured, but time-bombed, install.
However, don't do it on a machine that also has installed any other version of FM, Acrobat, and for TCS4; Illustrator, RH or any other TC component. The demo install is apt to wreck the older versions, requiring a complete uninstall and re-install, assuming you have the old media, keys, etc.
Yes, if you're on Win7/64 Pro, Ult or Ent, you could install the demo in XP Mode, but be sure that:
You can (CPU has Virtualization, and you're not on Win not-so-Premium or below), and
You are willing to pay the XPM penalty (loss of 1GB RAM for starters).
