I used an HP laptop, but that Acer looks pretty cool.
I have a 700tsv, and it works, but it can be hard to read if it's really sunny out. Since I'm near Seattle that's only going to be a problem for a couple months per year... I might upgrade to a transflective screen later but I'm satisfied with this for now.
I used the turn-on module discussed in the links below:
It works very well. It required two solder joints and one small hole drilled in to the laptop, which took and hour or two of careful work. No big deal though. I initially tried with an IBM laptop that was so challenging to work on that I gave up on it - some laptops make it very hard to get at the right conductors for the power button. I can't guess how hard it will be to solder the turn-on switch to your Acer - you'll have to take it apart and see for yourself.
Taking apart a perfectly healthy laptop is a bit daunting, but I've done it on three now with great success - all you have to do is find all of the right screws, take them out, and remember which screws need to go back into which holes. Take notes, maybe lay them out on a sheet of paper with an outline of the laptop drawn on it.
I'm using a 12v-to-120v inverter, you can get them for $30-$50. This of course feeds into my laptop's 120v power supply. I just ordered a 12v-to-19v power supply from www.epowersupply.us but I haven't received it yet. It certainly sounds like a more elegant solution.
I'm using iGuidance software for navigation (google it), I bought it bundled with a USB GPS receiver that has been working quite well for me so far (I've only had it a few days).
