That is a "con" for sure. But honestly, it's not that much different that running a standard laptop, right? According to everything I've read, inverter charging while flashing/scanning is a cardinal sin. You gotta run on straight battery. As it is, I don't own a computer with a battery that will last more than 30 minutes. So it was either drop $40 on a new battery for the wife's computer, $80 on a new battery for mine, or $80 for a fresh new windows tablet. I chose new hardware.
From the little bit of playing around I've done, I think the biggest hurdle will be the tiny, tiny screen. Need to find a small bluetooth keyboard with a touchpad. For now, my little girly fingers are getting the job done.
USB adapter is scheduled for delivery May 5th. I should be able to confirm function shortly thereafter. In the meantime, I'm keeping busy shopping for automotive tablet mounts.
