Okay that seems quite an understatement and game changing.
You can use as many daily magic item powers as you want ?
Just restricted by how many magic items you have.
Yes and no. This goes hand-in-hand with the new item rarity rules. Items with daily powers are usually uncommon or rare, which PCs can make and aren't as often found. This means that you have less items with daily powers in the first place.
Using the "no daily magic item limit" without the item rarity is very powerful (and unbalancing for artificers). Using both together works (though is unbalancing for artificers the other way).
