Following on from Scrap Princess' Google+ discussion about first level spells, I've been thinking about Identify. The problem - Identify identifies the properties of magical items. Therefore the implication is that you don't know what magic items will do unless you (A) randomly and dangerously activate them or (B) cast this particular spell that has no other function. If the GM is giving players magic items, or providing a space/setting that allows for the random acquisition of magic items, the implication is that the GM thinks it would be jolly good fun if the players had magic items. So why, then, the barrier to using them? Players either (A) waste one of the wizard's otherwise-useful slots with this otherwise-useless spell and then just carry on as if they knew the item's properties from the outset (and if the day consists of "ok we do nothing today except let the wizard identify the item so we're not going sperlunking with one less spell slot"
