EOS provides an operating system for developers to create decentralised blockchain-based applications.

1) EOS is user experience focused - making things easy for developers and end-users.

2) It builds on the Steemit technology which has successfully got traction with hundreds of thousands of users adopting the social media platform without needing to know or understand its blockchain infrastructure.

3) Dan Larimer EOS CTO built Steemit and Bitshares, both successful and pioneering. He is using the experience from both companies to develop EOS.

4) It's particularly scalable for enabling millions of users on a single application.

5) It's a good time to get in at the ground floor with the 1 year long ICO, though I'd say think long-term. As with Ethereum, smart contracts have a utility and traction amongst the business community evidenced by the Enterprise Ethereum Alliance.

My sense is this is worth considering if you're in it for the long-term and have the patience for going through the token purchasing process. The amount of money going in at the moment means the company may end up being over-valued in the short-term and so the price may go down initially.
