You won't be disappointed. The S230 is the same as the Ixus (I got mine in Singapore, hence the different name from the model sold in the US).
I would recommend getting a bigger memory card as well, especially if you're going to take the photos in high-quality format.
And if you don't have one, a card reader works well and they're inexpensive. I found that I rather drop the photos to my hard drive via the card reader, touch them up a little and crop the way I want in PhotoShop, then import into iPhoto.
