Hopefully I'll be adding a JuiceBee backup power supply to my gadget backpack - they are currently nearing the end of the funding campaign on Kickstarter

I changed my mind about some accessories.

The Rocketfish Miracast receiver is just a novelty that I'll never use.
For one thing, my TV only has one (working) HDMI port that I'm using for a BD player.
If I really want big screen computing, I'll run a long HDMI cable from a computer and use a remote keyboard and mouse, or the N7 with the Unified Remote app.

The Motorola S305 blue tooth headset pinches my ears and looks like it wont last.
It has flimsy, rattly buttons and fragile, open cell, non replaceable foam that you see on budget headphones.
I'm going to try to find some over the head, over the ear (or at least outside the ear) BT headphones that don't cost $300.
I'll have to find that online, I'm sure.

Both items have been returned.

My top 3 are a null set.

This is a cheap extra tablet and I plan to keep it that way. Not saying it is not an excellent tablet, but I have audio accessories etc for a different ecosystem.

As a bonus, avoiding cases and the like will keep this pleasantly portable device portable. It carries reasonably well in a front pants pocket but any bigger...
