Personally I've never really liked the 40mm focal length, however I liked the compact nature (I had the XS, a bit smaller but similar enough) and found it really fun to wander around with because of that. In the end I sold it for a few dollars as it was decentred and I didn't like it anyways, so wasn't bothered enough to pull it apart myself (it does sound like the buyer was able to fix it, and I hope they post their repair process on the forum here).
I think you're attracted to it for the fact it's a Limited, even with capable lenses on either side, but I think it's a different enough shooting experience that it's worth picking up - you can always resell if you don't find the magic in it. One also just popped up on the marketplace here at a nice price...
