I've got two, but I'm sure if I thought for a while there would be a lot more:
- I can fit my entire inventory into a tiny box or sack, including huge bulky armor and weapons.
- In a time of CIVIL WAR, there is NO market active for people who want others to improve or enchant their weapons or armor.
What are some of yours?
Morrowind had limits on how much you could store in containers, yes it makes sense, however it was also extremely annoying as you never has enough well placed storage places.
The container storage capacity was also low compared to player inventory
Had been really fun it the alchemy satchel on the table in Whiterun only took 15 potions

Now for the large containers the lack of categorization make you only use on container for one thing like weapon or armor.
