I developed Inputs because I was tired of waiting an undetermined amount of time for transactions to go through, especially when I am trading on multiple exchanges. The issue with confirmations is that you don't know how long it will be for a block to be produced - there sometimes are streaks of a hour without a single block.

Off chain transactions are also easier to use. The average user does not want to remember addresses - they want to use Bitcoin like PayPal instead of seeing a "Waiting for 0/6 confirmations"... Zzz.

The reception of our beta to those who know Bitcoin but are not power users who browse this forum have being universally positive - Bitcoin will never succeed if people need to sync 200 weeks of prior transactions, have all their 100% payments public , and worry about keeping their private key safe in case of a natural disaster. We're here to fill this need.
