Just make double sure that the input label on everything says something around 100-250v.

You mean the Adapter that plugs into the outlet? Take more than one with you, they can fail.
I am more concerned about leaving one behind. Never have had one fail.
Mshore,
If you have a Radio Shack near you, you can find the adapters there too.
You can also buy them at hardware stores, Target and Walmart.
They are also in any gift/magazine store in almost all major Italian airports. even a large Co-Op will have them.
ms,
For ungrounded appliances, which is most likely the case with the devices you mentoned, this is the type of Plug Adaptor to use for Italy.....
It's always good to have a few extra, since they're small and easy to misplace or forget in the room. If any of the appliances you're using have a ground (third) pin, then a different style will be required.
It's important to check the Input Voltage ratings on the Chargers for each device. It these state, "Input 100-240 VAC" then they will work fine in Europe with only a Plug Adaptor. The Apple products will most certainly have that rating.
