It can do 20 Pflops with 1.6 million processors, so 12.5Gflops per processor, but with 1.6TB of memory, it means its only got 1Mb per processor.
The other seven megabits per processor are used for parity checking.
It's not just about switching operators. The widespread lockin lets the operators dictate what features the phones have, and it has damaged the US market significantly. In Europe, a lot of people go for the contract option, but the large unlocked market ensures that operators don't have power over the phone manufacturers. I'm constantly reading articles raving about features we've had for years that have nothing to do with building networks.
If you don't get a price break for buying a phone on your own it just means the carriers have so much power they can screw you over. That's not a sign of a healthy market.
As for people being happy with what comes installed, sure, but the effect of lockin on competition retards progress, and prevents anyone who does care from installing what they want. There is NO benefit to the consumer in such a system.
