Considering Batterfly's price on it is approximately 2.6X as much as an 888, I wonder how many they are going to sell.

The form factor isn't incredibly smaller, or anything.
I have used my two 888's at the same time and it's nice having two separate stands. It seems like I would usually take the time to use two irons when doing two parts of a batch process. And only using one at a time, with the other iron pushed off to the side.
If just building a prototype, I would typically just choose the best tip that can do it all. Or stop and change tips... because really it's probably not that big a deal if prototyping.
