I'm planning on upgrading the little 160 GB 5400 RPM hard drive to a
larger 320 or 500 GB 7200 RPM unit and the 1GB of RAM to at least 2 GB
in my Acer Aspire One 10.1" netbook.
I took pictures of the process to upgrade either piece of hardware and
created a quick guide to help out any other owners.
It should be the same procedure for most 8.9", 10.1" and 11.6" Acer
Aspire One netbooks.
Here's the guide -

I hope someone finds it to be useful.
Cheers,
