For me the main things that would make it really *super* useful are:
1: Snapshot restore function being speedy (even after a while)- in this item alone, CTM potentially differentiates itself from many/almost all other restore/re-image options (to define; to me speedy equals <5 mins in all situations, though the faster the better)
2: Reliable and stable - installable on any set-up (2.8 would install on some of our computers but not others!) and not leading to any later boot problems as seems to have been the case on one PC I installed 2.8 on
3: Compatible with a dual-OS system
4: Free for charitable use (or very low cost for multiple PCs for charitable use)
5: Available soon! :-)
