As far as non combat utility for wizards between the editions, I don't think the gap is as large as some people may see initially. Sure, if you look through the back of the 3.x book, you see a HUGE list of spells.
If we ignore damage type spells for a moment, 4E powers that deal no damage, and do other things are far less than the ones then in 3.x. However, when you count Rituals, it's not enough simply to compare the number of rituals with the number of spells. The average ritual in 4E combines at least 2 different versions of a 3.x spell. In 3.x, you would have the effectiveness of the spell revealed by the level OF the spell. In 4E, it is instead one spell, that becomes more powerful (usually via a skill check), as you level. So things like discern lies, comprehend languages, passwall, forbiddence, etc while they appear as one spell or ritual, their 3.x equivelent could be anywhere between 2 and 5 spells.
Yes, there are some that are missing still, create water comes to mind. But really, is it that hard to make up a ritual to create water of the top of your head.
(ex. Make an arcana check, divide that result by 2, thats the number of gallons you can make. Simple, no?)
