> My phone's battery would last 2 seconds if it used the processor my laptop would use. And my laptop would be slow as shit if it used a processor compatible with a mobile phone. A powerful ARM CPU, down-clocked and/or in a big.little configuration would cover those cases, somewhat. Low clock during mobile operation, higher clock+power usage when docked in a non-battery situation. The concept seems to work fine with phones + ARM Chromebooks that are out there now. > Aside from hobbyists, I'm not sure anyone actually wants this product. Open to some feedback here! Still true. Most people probably don't want to upgrade that often, deal with their phone not working when the CPU is stuck into a dock, etc. I still like the idea of this kind of upgradeable hardware. Maybe it would make more sense to have different form factors for cards, with adapters to connect smaller cards into larger enclosures. It seems like that kind of schema would provide the greatest coverage of different use-cases (although, it'd require either standard buses/data connections through the entire line of hardware, or conversion hardware included in the card adapters).
