If I remember right and it has been a while and I didn't do real in depth research since I knew the specs wouldn't matter to her as much as her impression the tour has a slightly faster processor though I don't remember the architecture type if they are the same then slight bump to the tour on that.  Screen resolution was maybe a little higher but on a screen that small personally it isn't that big of a deal unless it is significant which in my recollection it wasn't significant and the tour may have a little more memory for apps.  Don't hold me to those since as I say I just kind of overviewed them to get a feel for which 3 or 4 to narrow our search to.  Figuring she would look at several but I could give my little in put as to tech specs in as much as they matter to her.
