I agree, but the 5G analysts all have aggregation in their predictions. Of course, there is also the arguement that if you offer it, they will come (in this case applications e haven't imagined yet.)

I don't think band aggregation matters for phones. What's the use case for needing 1 Gbps bandwidth to your phone instead of 200 Mbps?

I don't believe there's a use case for 1 Gbps to your home for all your devices, let alone to a single handheld device. If you think there is such a use case today or in the next five years, and it isn't niche (i.e. "I work at home with multi-gigabyte CAD files on my corporate file server" or something like that which does not apply to 99.9% of the population) please let me know. I've asked this question many times over the past few years, and no one can come up with anything, other than ridiculous pie in the sky stuff like someday streaming 8Kp120 video to an entire family.

Yes, Apple has improved reception since attenna-gate, but is unprepared for aggregation of bands just over the horizon.

Gert Frolund Pedersen, from Aalborg University in Denmark does some testing every  year, you can easily find the results on Google.

I have had an iPhone 6S plus since it was launched. No issues with calls whichever hand I hold it in. Maybe its a problem in areas with weak signals, but that's much less of an issue today than when the iPhone 4 came out.

Yes, Apple still has not solved antenna-gate, but has merely "improved" reception, hoping it wil go away. The only way to solve it is RF MEMS realtime capacitive switches.

Good antenna tuning or not, Apple does not seem to have a good grip on their RF - at least not according to this report. If you have an Iphone 6S plus, do not hold it in your left hand.... https://www.pts.se/upload/Rapporter/Tele/2016/MobilephoneTest2016-augusti-2016.pdf

Yes, Tim Cook is to blame, but its not as bad as you make it sound. Apple has more integration that an other smartphone maker--that is the legacy that Cook is contiuing and it is a good one. Also, you are right, Apple could develop their own MEMS technology, but it makes more sense for them to acquire it, according to the analysts. MEMS usually resides on a different die--thus making the phone bigger--but Cavendish, for instance, can bury the MEMS part inside standard CMOS layers making it the perfect target for acquisition. Maybe that is why is has such a long and prestigious list of backers.

Certainly their list of investors currently sound interesting...

Maybe Qualcomm might be interested in a majority stake:-)

To elaborate on your last sentences:
1/ People have forgotten what a mobile phone was for
2/ Anyway, when signal is week, they blame operator
