My original Cuisinart processor was at least 50 years old and when a plastic connector broke during the holidays, I replaced my aging Cuisinart with a new 7-cup Cuisinart Food Processor.  I was delightfully amazed at the design and functionality changes in the new 7-cup version- how the accessories can be stored inside the main bowl, how it assembles and disassembles, how easy it is to wash. Most importantly, regarding ease and effectiveness of use, the blades are marked as to function and are very sharp, effortlessly grating, slicing, and chopping.  The modern design and color have prompted me to leave it out on my kitchen counter for easy access, instead of storing it away in the pantry.    
My new Cuisinart is definitely going to help me save time with food preparation.
