bigger issue is probably around the components fitting in to the bloks, with interfaces and unit costs a problem. say a Wifi module, its probably got a dozen or two pin outs to the main CPU, not two or four like the presentation.
Not necessarily true - you can get wifi adapters that attach by USB which only have 4 connectors. Ditto many, many other peripherals. So long as the larger components have enough connectors to the main logic board then I can't see a problem as most will be just fine on 4.
It's TRIGGERS BROOM!
On closer inspection this idea just doesn't hold water.
The idea is years old!
All my calls were blocked.
In an ideal world, a top idea. In the world we live in? Unworkable. No phone manafacturer is going to support this. A lifetime of upgrading, buying new blocks, sourcing what you need for the best price? No thanks, I'll stick to the new Iphone I get every 2 years thanks. Plus Youtube has a million tutorials on it to replace parts on normal phones.
