I'm sure you're not the only one.
I got a mini today, after thinking I wouldn't, I decided to give it a go anyway.
For some people it's an either/or proposition, they're not interested in owning both products. I don't see it that way.
For work, photo editing and the like, I'll use a full powered, full sized iPad with a Retina display. I currently have a 3rd gen, which will be upgraded to a 4th when the LTE models come out. I was honestly going to get an LTE 3rd gen anyway, because my needs have changed. Now that it's been updated, I might as well get the newer one.
As for the Mini...I love the weight and the way it handles. It is more difficult to read which is a combination of the smaller size and the lower pixel density. All that said, I went with it as a remote for Apple TV/Home Theater and for home automation items that I'm going to set up. It'll also be nice for my girlfriend to have one to use if she's over and I take mine to work with me. Her daughter (5 years old) also likes to play with the iPad. I'd rather have her break something that costs $330 instead of $500. While I'd love a Retina display in it, it isn't really a dealbreaker for those uses.
Both products are strong in their own ways. If one must have one or the other, then sure, the full size iPad is the better choice, but it's not like either are bad.
