XS or XSI?

So I have decided in the name of cuteness *aka my child* I must get a different camera

I have done a lot of chatting with people and read a bunch online and am now torn between the Canon XS or XSI

I guess you will find out tonight what I get after I post some awesome new pics of Simon, the dogs, Chris and whatever else happens to be in the way of my lens

Wish me luck

Edit-
It's arrived! I went with the XS!
