I'll follow up my original comment about the Motion LE1600 w/ Bluetooth:

1. I've tried a Toshiba tablet, and an HP tablet.
2. I've tried wired and Bluetooth
3. I've tried battery and wired power

Results:

1. Motion is by far the best screen and best ergonomics for the plane.  That
said, it is large for my 360.
2. I use a mount that secures the tablet on an adjustable arm attached to
the center console.  It works very well.
3. I have NEVER had a problem with the bluetooth GPS nor bluetooth WxWorx
receiver.  Both work flawlessly once powered up.  However, don't let the
notebook, NOR THE PORT, "sleep" while using in the plane - you will end up
having to reconfigure in flight.  That happened to me once or twice, then I
stopped letting it sleep and haven't had a problem since.
4. I was offered a LS800 (the smaller version), but with all the menus, etc.
on the screen, it really made the smaller screen less usable.  I prefer the
larger screen.
5. I generally use wired power.  I built a box that contains: GPS, WxWorx
receiver, antenna, USB Hub and power supply.  It has an output mini-jack for
the notebook power cord, and an input for the cigarette lighter power cord.
Works well though sometimes the GPS and WxWorx antenna's fight each other so
I remove the GPS and use it on the dash on its own battery power.
6. My wife likes to play solitaire while we fly.
7. The hard drive in the Motion is very sensitive to altitude- dies at 10k
feet.  My Toshiba was just fine to 18k feet.
8. I use FlightPrep Chartchase Professional and am very happy with the
product.  I mainly use the moving maps (VFR & Low alt), and approach plates.
