..or sell some of those devices and purchase..

a Sony UX380N/280P/390N..

or an oqo model 2(you can find them for a decent deal, but i dont throw my support behind this device.. if it matters..)

or an Raon Digital Everun

I just can't imagine carrying 6 devices w/nearly overlapping capabilities out of the house each day!!!

I wish you the best of luck on your decision!
