I'm not sure laptops could or should be considered embedded devices.
Think modded 'switch' or 'router' instead. The idea is that if I plug
in an appliance, whether at the start of the day or when I moved in the
lab or to another lab or when I swap CF cards[1], by the time I can get
my hand over to the keyboard it should be ready to use.
Maybe for a netbook it might be useful, but I don't use it there. The
time I seem to lose on the netbooks and notebooks is caused by the bios
and bootloader. I chose not to use it on the production servers. The
only important thing with the servers was to come up automatically when
power was restored.

[1] e.g. swapping cards is almost infinitely faster than doing a
restoration from backup. the backup would have to be on a removable
device anyway. since I have 'extra' time to fiddle now, I've bought
more hardware and test different arrangments:

Eventually I will settle on what is best for my own use and leave it at
that until later.
