VRS and the Memory Player both have the same capabilities as the Sooloos.
No they don't. NOTHING I have seen has the same capabilities as the Sooloos in terms of the quality of the touchscreen and the GUI.
VRS has a website that is basically down and they were using J. River Media software previously (available for free to anyone)...not anywhere near as cool as the Sooloos. And the memory player seems even less like it.
