To me it is a very logical layout, no need to consult the manual to figure out how to get around. My only complaint is the scroll wheel, you kinda have to use a fingernail to catch one of the edges to move it around.

If you have any questions for me, please send an email and I'll see what I can do.
You can also visit the vp8350 page on Vosonic's website.
dpreview's storage and media forum is also a great place to learn more about this and many other personal storage devices (PSD).
Disclaimer: I have no affiliation with Vosonic, just a satisfied customer who found very little info posted about this product when I bought it and figured this site might help someone in their search for a PSD.
