Hi David,
Welcome to Laptop GPS World.
Yes, you can turn your Acer Aspire One, or any other netbook, or mini-laptop, into a GPS navigation device. All you need is to install
GPS software for netbook (about $40 to $90) & a USB or Bluetooth GPS receiver (about $40 to $60).
Look around this forum, you will find several postings by people who use Acer Aspire One, just like you.
