They'll start making them if they start getting big. I think this is one of the few MP3 players with Android running on it, so I can see it picking up big time.
My biggest concern with this player is that I don't know if I should root or not. Haha.
I will be ordering a new pair of headphones that do this thing justice. I read that the SGP5.0 has one of the best sound drivers and I feel their stock earbuds aren't worth anything so I'll be looking around for some nice IEM's or over-the-head headphones.
If you wanna do the same, there's a website dedicated to this stuff. It's head-fi.org.
Lemme know how yours is playing out.
Also, any suggested apps?
