I'm late to the party, but I guess modulariry would be a plus. For example, CPUs don't grow in big leaps of capacity anymore, it would make sense to rediscover the practice of upgrading CPU, RAM, battery, storage, etc. instead of whole devices. This could put a significant dent in ewaste for bigger devices.
