A few ideas that are currently being developed for consumers like me and you using blockchain, Bitcoin and Ethereum are:

Golem. Decentralized P2P supercomputer that pays people to use their idle computer time.
IPFS Interplanetary File System. Think of it as rewiring and re-routing the entire internet so that trains run and stop on time and go where they need to go all while greatly reducing redundancy.
Coinbase. Cryptocurrency exchange for buying and selling Bitcoin and Ethereum for dollars.
Bitfury. Develops and delivers both the software and the hardware solutions necessary for businesses, governments, organizations and individuals to securely move an asset across the Blockchain.

This is only a taste of what blockchains have provided for people around the world. Keep in mind, there are many, many more applications being developed and released into many different industries.
