Most electronic products, especially those using switch-mode DC power supplies, do use transformers. The reason is that the transformer provides galvanic isolation from the AC mains. This helps prevent transients like lightning strikes from propagating through the device. Also, it prevents the wrong parts from becoming "hot" because the cord is plugged in backwards.
Products that do not have transformers have much more stringent requirements for creepage and clearance distances, and are usually simple devices. A drill, for example. Hard to do with an electronic device with lots of buttons and slots.
The high-frequency operation of a switch-mode power supply does allow the magnetics (transformers and inductors) to be much smaller than their 60 Hz linear counterparts, but they are still there.

10g is not a lot of acceleration for electronics, as long as large components are securely fastened (even with tie-wraps), and there are no moving parts.
The only non-solid-state parts on the design are the connectors, which can handle hundreds or thousands of g's of acceleration without "bouncing" on the pins.
PC-104 is designed for high-stress applications such as this.
Does that also mean talk-free? Most radio stations have "commercial-free hours" which includes a lot of self-advertising, saying the call letters every few seconds, etc.
DJs that blab over the beginning of songs and cut them off early are going directly to hell.

I'd only buy the set if I could guarantee that my money buys the exact slice of pizza you choke on.

Totally wrong.

Luke looks at a little screen on his X-Wing that displays the words. You can see it.

Did you get that memo about the new cover sheets on the TPS reports?

I'm sure that this device, when activated, invariably provides a plastic cup filled with a liquid that is almost, but not quite, entirely unlike tea.
John Dvorak must still think digital watches are a pretty neat idea.
There's a few programmers I haven't seen in years, but they still respond to e-mails. Now I have an idea where to start looking.
