Yeah - it's a failure of a product. Estimates are that it's sold 2m units in a weekend. Total failure!
Production of the 5C hasn't slowed down the 5S production:
- The 5C is using year old components, of which there will likely be stockpiles.
- The 5S is using brand new components - which are, of course, going to take longer to produce.
- Availability isn't going to effect sales that negatively.
- Of course the 5S is going to be more popular. People that buy on day one are likely to want the latest and greatest.
But yeah, have a tantrum on a message board because you can't get one straight away.
