I have the Librands foot locker and it has two major advantages and one disadvantage over not having anything.
Whilst I wouldn't keep a camera in there, as one of the adverts shows, as it would probably be shaken to bits, it's really useful to have a secure place to keep documents like breakdown cover, insurance etc. As a footrest my wife loves it as she is much more comfortable and feels more secure in the car, it was her idea when we were speccing up the new car.
My youngest son is not so keen as he has very long legs and was able to stretch out his legs in our last two Morgan's but can't in this one.
If you do get one you might have to re glue the rubber facing strips as modern Morgan's have very effective heaters and the heat melted the glue used on mine.
Finally, unless you are a contortionist, to open and shut the storage compartment you have to get out of the car and lean into the footwell so personally I wouldn't use it to store items that you need regular acces to.
