Pokusiłem się jeszcze o małe porównanie "serca" EFC-01 i innego, z kontrolera systemu Grenton. I okazuje się, że to co działa w EFC-01 jest nawet potężniejsze niż kontroler CLU Grentona. A mimo to Grenton daje większe możliwości. Czyli dochodzimy w tym miejscu po raz kolejny do wniosku, że nie sprzęt jest najważniejszy, a to jak ktoś potrafi go wykorzystać i oprogramować.
