Not on the Acer Aspire One but on the MSI Wind Notebook, which isn't all
that different. I have installed Ubuntu (and many other distros!) from my
external USB DVD drive and also from a flash drive. I've found Unetbootin
makes it easy to install most distros onto a flash drive.

Other than that the installation is pretty straightforward. I should mention
that I replaced my original WiFi card with an Atheros one. Enabling WiFi may
be an issue to be resolved on your device.

Sometimes you can't see the bottom of windows which are expecting a 4:3
aspect screen. Using alt when you drag usually makes it possible to lift the
screen enough to see the buttons. Or you may use alt- and the key letter,
usually C(lose) or F(orward).

Have any of you had any experience installing and using Ubuntu on an
Acer Asprie One? If so what do I need? What do you recommend?

Reply: No, but I have extensive experience with the eeePC both with an Atom
processor and with a Celeron processor. I have used everything that will install
and currently my favourites are Ubuntu 8.10 and eeeBuntu NBR (netbook remix)
based on 8.10.

Quote: In order to install Ubuntu I assume I will need an external USB CD/DVD
drive or a 1GB thumb drive.

Reply: I use Unetbootin to make a bootable usb stick and it works well with most
distros. Unetbootin is in the repos or it can be run as a downloadable binary to
run from your desktop. I have an external DVD drive that I can run as well, but
it is larger than my netbook.

Quote: What are your thoughts on an external larger LCD display, external hard
drive, keyboard or mouse? After the Ubuntu OS is installed what
accessories do you recommend.

Reply: I have used an external display, but it kind of defeats the purpose of
having a tiny netbook by being tied down to one loaction. I use an external
mouse, but I forced myself to get used to the keyboard and touchpad. I have
several SD cards with different OSes on them and lots of usb keys full of music,
podcasts, videos, recipes and the like. I have a Logitech bluetooth headset that
I use when I listen to music or podcasts that allows me to roam around the room.
I find less is more when it comes to netbooks. The more you encumber yourself
with gadgets the less you are likely to use it.

I have Ubuntu 8.1 dual-booting on my Aspire one. The easiest way is to
use a computer with CD drive and boot from the Ubuntu CD, then create
a thumb drive from there. Look under "System -> Create a USB startup
disk". I have been unable to create a workable USB disk on any but 1
GByte sticks, so you may have a problem with 2 GB or larger sticks.
Make sure the USB drive is formatted FAT16.

Set your netbook to boot from USB and install. I also had to install
madwifi to get the wireless working.

I found that xfce is a better fit for the netbook, so you might have
better results installing Xubuntu.

I have a old Sony 1 GB thumb drive and purchased a 8 GB Sandisk
Curser drive over the holidays. Tried to make the Sandisk Ubuntu 8.10
bootable. It and/or the computer try to boot but failed. Maybe that
is the why.

In a earlier post I ask about accessories. Those are for the computer
room at home. Things to make it easier to use there, although I have
2 computers that have all the power I need there. The accessories was
to be able to configure and use the Asprie in the computer room at
home only. However, a big thumb drive, SD modules, little things like
that would make it easier to use in the field.

Roy, Leslie, and Henry, thanks. Thanks for sticking you heads up. I'm
sure I'll be pick'n your brains on this subject in the near future.
