UPS Back-up Recommendations

[Raelynn]

Seperate question: Both my wife and I have laptops as primary PCs and I'm wondering, should I be using a UPS system to firewall the laptops' AC adaptors from the house, or are we okay with the AC adapters alone? Also, how much damage am I doing to my laptop using the power outlets while traveling on the Acela (Amtrak's business service serving DC, Boston and major cities between) with the power supply going in and out once an hour or more?

I'm not 100% sure about this, but since laptops generally have converters in the power supplies and have batteries, the change in power supply affects them less, but it does not necessarily mean there's no affect. I would think that most of the damage would be eaten by the power supply rather than the laptop.

If they did take damage from losing power, then someone who moves around a lot, thus unplugging the laptop, would be in for a lot of trouble. :)
