For the record, I still see items like a bag of holding, a feather boat and portable hole even in the 4E PHB's smaller magic item selection. Adventurer's Vault has plenty more non-combat specific items and even some combat items which might be creatively applied to non-combat situations.
Yup.
It's a funny thing. When I first bought the Adventurer's Vault, it seemed like just an extension of the PHB item list - an endless parade of weapons, armor, implements, and amulets, differing only in the numbers and keywords attached to each. It seemed like a fun little toy for my inner optimizer, but nothing particularly interesting.
Then, as I was creating a cleric and flipping through the AV to choose the exact right suit of chain mail and holy symbol, I stumbled across the Wondrous Items section, and realized that there was a great deal more to the AV than I'd thought. The consumables section also had a lot of good stuff. I hope the next AV builds on this.
