I didn't knew that people with the appropriate power to do otherwise still fell in the same trap they did back then with GSM, when US and a few others clung onto world-incompatible technology when the rest of the workd went with GSM.
Well, those people act just like Apple, they don't want to co-operate and have standards...

Seriously, using bandwidths is that old global super power politics and somehow US has to always use different frequencies than the rest of the world. LTE is LTE everywhere, but you need additional things to that modem than that baseband chip.
the 90% would have been happier since they would save a $30 from an EC-based card reader. But your hypothesis seems reasonable, but I still don'T understand. Would upgraders really go for a more cumbersome 17" if they wanted upgradeability? Because if the newer models still don't sport the necessary port.. What would be the point in upgrading?
I went for the 17", but also to have hi res matte screen. Maybe things now change when cheapest new ipad have more resolution than the most expensive MBP.
But I think most of upgraders just bit their lip and either kept their old hardware and didn't upgrade, went to the world of "other PC's" or bought used hardware like me.
Or they did what Apple wanted to do; not to buy a 3rd party card or adapter, but a whole new computer.
Eg. "I need to have 2 fw ports. I used to have 1 mbp with 1 fw port and 1 fw EC card. Now I use 2 mbp's."
Or "I used to have my AJA sdi-card plugged to my EC slot, but then I had to buy MP. Then they released mbp with tb! I instantly bought one and new AJA sdi-card with tb port! Only $10k and I'm back where I started and smiling happily!"
Hmmm, btw, could I have tb controller EC card to my mbp? Nope, of course...
I'd guess that very few would have complained that they had to buy $30 card reader. Most of us had already bought a lot of them (you know, sd isn't the only standard in memory cards and especially not in "pro" world..).
WHERE can you actually buy 100GB Blu Rays? Even in large stores I could never find one above 50GB, as I could also never find DVD+RW.
Maybe you aren't looking very hard?

I don't need 100GB bd's now, but I will use them in the lifespan of my burner.
I usually think about the future when I buy something. Not just what I need today.
Looks interesting, but what about reliability? Having three points of failure in the same drive doesn't even provide redundancy in case one drive fails. For some time I was still able to run a PC without a HDD out of a live Linux distribution and a USB key. Even my current Mac setup can be run without an internal HDD, without the ODD, or without the external clone.
3 points of failure if you put ssd inside ODD?
How come?
And if you put all those combined with hdd and card reader and usb port inside your laptop how many points of failure you are carrying?
Hybrid drive is just an idea how to make things more compact. You can always buy separate ODD & ssd, if you like.
