Block time will matter for the new generation of financial platforms we're starting to see, like Mastercoin, Colored Coins and Counterparty. I'm already seeing complaints that using the Bitcoin block chain is too slow for an exchange or betting. Orders take ten minutes to place and even longer to execute and confirm. I0coin is a great choice for these platforms because it has the speed and security.
I don't think you understood what I wrote in my last post... (technology) you're still thinking in the past. Look to the future, think outside the box.
Are you saying Bitcoin is outdated? There are still niches that i0coin can fill like a stable, secure, high block rate platform for these financial platforms. These have just started arriving, and Bitcoin devs are actually resisting support for these.
