* Everything was free phone at the low end and $199 at the top end
One of my friends bought a Palm Phone.
* Apps were pre-loaded onto phones
This may be true.
* Carriers drove handset manufacturers choice of OS
Maybe handset manufacturers, Palm, Blackberry, Nokia had their own OS.
* No one ever waited for a phone
This may be true.
* Manufacturers did not care about UI/UX
I read lots of reviews where people praised the Nokia UI over the alternatives.
* Phones sold on spec sheets
Spec Sheets?
I really don't think this was true for people I knew. People I knew bought phones as Jewelery. They wanted small size, and long battery life.
