Thats true but an android player isn't really necessary especially when almost everyone, who is able to afford the dx100, already has an iphone or android mobile phone.
Moreover, android doesn't add any value in terms of music playback.
However, if the 802 turns out to be a disappointment, dx100 will be my next DAP
Not necessarily my friend. What android adds is the ability to use other music players which is a great addition. The stock player as of right now has some bugs which I don't like at all. Power Amp is flawless IMO with the DX100 and at least addresses my issues with the Stock player. Who knows it may lead to an update where all the music players would be able to use the 24/192 playback and that would be a great feature allowing you for more options including different sound signatures.
