It was this statement that troubled me...
" The missing ling (sic) is that there is another source of income that must be secure to undertake this purchase but has not yet been announced".
I contend that the company organized this acquisition based on current resources, and I think the structure of the deal suggests likewise.
I accept your explanation and tend to agree there are many waiting in the wings for the show to begin; the curtain has yet to rise though.
As for PET, it remains an enigma; how or when we see its' re-emergence is unknown. I do like the Apple link, and certainly TB hasn't been sitting around drinking coffee for the last 2 years, but thus far there is nothing to specifically tie the two together.
