yeah; completely understandable. Just that if you're stationary with the tablet when listening to music (unless you're one of those people that listen to music on their tablet with it in your pocket or coat) then a powered usb hub would be the easiest and quickest solution. unless you want to get a portable wifi disk like this one http://forum.xda-developers.com/showthread.php?t=2169383 (SIDENOTE: I wrote the review for this on xda) and your tablet will be able to access the music on your flashdrive when connected to the wifi disk and still be connected to the internet.
I think Patriot makes one of those wifi harddrive/hotspot things too (gauntlet node?). I thought about going that rout at one point too, portability really isnt a huge issue, the tablet sits on my desk at work to play music, then comes home with me. I leave my headphones/amp at work in a locked file cabinet. Searching through my options is fun for a slow day at work like today
@ Panda, I know I cannot get a P-H (and a little bummed :-P ), I read up on it and was quite impressed with your efforts in the whole process of getting production units.
