No official numbers have ever been published tp my knowledge via the enTourage website, but we know somewhere between 11,000 and 14,000 or more Pocket eDGes were sold by HSN since they put it on sale (as shown on the HSN "Number of Units Sold" ticker).

The Pocket eDGe officially goes on sale this month, with the enTourage website indicating a Nov 8 launch date. The HSN listing was effectively a pre-sale, and the Amazon, J&R, and other sites being pre-orders, which is why availability seems spotty (i.e., it's not actually available yet , other than via HSN).
