I picked up the laptop due to issues we had with reliability this year. We picked up 3 at the start of the year, and are down to 1 reliably working. One of them won't get past the bootloader on a regular basis, but if you sit on it with a serial console and spam reset it will eventually start.
The other refuses to power up at all. I suspect the first case was due to handling for cading a case, the second, due to a miscommunication, was connected to VBatt, not VReg(12).
The problem with the laptop form factor is the weight. I feel that with a good case and sufficient QA to make sure the device is connected to the regulated 12v supply this will be a reliable system for next year.
I'm also working on a UPS that would conform with this years regulations for giving about 30 seconds of power to safely shut down a co-processor. That being said, in the past 3 years, we haven't had issues with sudden power removal impacting the coprocessors.
