They've decided to delay the mass roll-out of the devices, with Jack Dorsey telling users that the company "released parts of Square before they were fully baked." That coincides with what our readers were saying in the comments on the original interview -- that the reader devices were taking a long time to be shipped out to users. Dorsey also agreed with the other issue our commenters brought up (that the service's transaction limits, which Square originally put in place to counteract fraud, are too low), and said that those limits would be addressed soon.
Dorsey doesn't say how "soon" that may be -- there's still no ETA on when the readers will go out, and Square is still working on how exactly it will change or update those transaction limits. Basically, there is no fix in sight for those frustrated by the company so far.
So it looks like Square isn't quite where it wants to be yet. But then again, think about the problems it's having: it can't keep up with demand for free readers, and people want to transfer even more money through the service. Those are pretty good problems to have. Square is definitely taking its time while working out the kinks, but the fact that it just can't keep up with demand is far from a condemnation of their business model.
