I want a case as small as possible for mobility, and this is the smallest case I can find. I don't need space for batteries and memory cards. I usually charge the batteries full before I go on a day trip so there is no need for battery space. The fully charged batteries last well over a day even with some video clips. Secondly with memory card so cheap nowdays I don't need to carry extra cards with me unless I want to shoot tons of video. I got a 2GB high speed card for around $40. A 4GB can be ordered for around $90. In fact I wish it could be smaller by eliminating the space for accessories so it wouldn't look fat while it is on a belt. I got a Tamrac 5693 Digital 3 earlier. But I like this one better.
