Okey dokey .. I'm gonna post the instructions here anyway.....
On the Windows PC, start Universal USB Installer, and at ..
Step 1 .. In the drop down list, select PeppermintOS (Three)
Step 2 .. point it at the ISO image you downloaded
Step 3 .. Choose your (already plugged in >= 1GB) USB stick .. probably best to let it format it too, so backup its contents first.
Step 4 .. Set the slider to the largest persistence file it will allow you.. so you can save changes. (if you want to test drive it first)
Here's a pic of the Universal USB Installer interface
Click
Create .. and wait till it's done .. it will take a while, and *may* appear to have stopped .. but just
wait till it says it's "Done" .. as in the following pic

Once the LiveUSB has been created, click
Close, plug it into your AA1, then turn ON your AA1 .. as soon as you see the first screen (Acer Empowering People), hit the
F12 key to access the boot device selection screen .. and select the
USB HDD as the drive to boot from and hit
Enter to boot.
(If it doesn't offer you a USB HDD, and instead lists a USB
FDD, let me know)
When asked, select "
Try Peppermint"
NOT "
Install Peppermint"
Be aware .. running from a USB stick will be quite a bit slower that running it from the internal SSD after installation, so don't draw any conclusions about speed at this point

(it may also be less stable .. remember a LiveUSB is designed
primarily as an installation media and recovery disk, but can also be used to "test drive" Linux)
I *can* tell you that once installed, it takes
slightly longer to boot than Linpus Lite .. but once booted it loads/runs applications just as quickly .. and has access to all the latest software.
Let us know when you're at the Peppermint desktop and we'll explain how to connect to your wireless network.
Oh, and how to change the default wallpaper .. which IIRC kinda sucked in Peppermint 3
