So it seems to be clear that there are a lot of enthusiasts waiting for this DAP, and that the main issue will be the storage.
As said, they still provide their xperia phones with a microSD reader, so I can't understand why Sony shouldn''t put a card reader in this DAP!
Otherwise, they must provide the ZX1 with a big storage, but due to the costs of the flash memory today, we might pay 2/3 of the price only for the memory!!
Maybe the only solution is to provide the device with a hdd similar to the one built in the ipod classic.
There are alot of people here interested it seems although many will get scared off if this device sells north of $800.
