This is older, but: PEX.
My conclusion: the “ex” ending is hot in product naming.
And secondarily: capitalization is flexible.
NEX is from Sony’s αNEX series of cameras—Sony’s impressive counter to the micro four thirds lines offered not long ago by Olympus and Panasonic.
Plex is software we’re using these days to replace cable, which we dropped over the winter (even though it’s a legit biz expense for Someone).
PEX is “cross-linked polyethylene” pipe or tubing. Think snap-together plumbing in the Great White North. Don’t ask what it may be leaching into the water (I tell myself).
Plex and PEX aside, my new camera lust* is the αNEX line (especially this one). Nif-tee!
* This in spite of the fact that we have three fine up-to-date digital cameras, including the iPhone.
