The only case type which works for me is the holster style carried on the belt. My current
Nutshell is a fine specimen of this breed, a sturdy yet elegant leather case that looks, feels, and smells great. But it does not have what I would call reliable storage for memory cards.
The Krusell Universal Horizontic looks like an inexpensive alternative, judging by photos (
e.g. here), with a department for storage cards.
I would appreciate if people who use or have used this case could share their experience with me.
