Hello hero her> Mobile phones are a USB terminal device and they also need a HOST, and not her> all mobile phones have a USB port. 1) Yes, not everything is simple with mobile phones - their manufacturers usually don’t allow load software into them from flash drives and in every possible way limit the access of third-party software to mobile phone Obviously, it is for the benefit of the user - there will be no viruses, etc. Although Recently in some review there was a mobile phone that allowed all this (not a smartphone) - need this type. Now there are few of them, but progress does not stand still :) ; 2) New mobile phones usually have USB, this is a standard for mobile devices, according to it they work both as modems and as a flash drive; 3) Host is ZX; 4) Mobile is not necessary. Mobile is optimal in this application from the point of view from the user's point of view - you already carry it with you all the time, and you don't need any other carry extra weight, it lasts a long time on one battery charge, it has music synthesizer and full color display.

Hello fan All mp3 flash players have USB, some also have card readers, usually SD/MMC, there are practically no CF readers (CF is considered an obsolete format and is under they do practically nothing new). But it is CF that can be read using the IDE, and for SD/MMC it is necessary to invent a new controller. When reading from cards the player generally nothing to do with it. Only USB remains. USB is really relevant. This is for three order of magnitude more relevant than any other hard and software developments for ZX. This what the ZX needs to survive. This is the main thing you need. Everything else - tertiary.
