I have an Acer Aspire One netbook and I want run Linux on it, but I don't know which distribution I should choose. It has a 1.66 GHz Intel Atom processor and about 1 GB RAM, so it shouldn't be too heavy.
I have an Acer Aspire One D257 and have a couple problems, there is a small pause that I only notice when programming  and the sound has stopped working in 12.04, but other then that I think Ubuntu is fine, if a little slower than on a full blown Desktop computer or laptop.
If speed is important to you you might want to consider Xfce or Xubuntu which uses Xfce instead of Gnome or Unity by default.
After trying a number of distros, I have finally settled on LXLE, based on Lubuntu, to run on my Acer Aspire One 722. It works really well if you do this:
Set boot order (F2 on boot) with NETWORK boot as first option, USB HDD second and internal HDD third.
Boot LXLE from a usb stick use unetbootin to install the ISO in Linux, or Yumi or similar in Windows)
Link to your wi-fi and make sure the mouse cursor moves - try moving it around for a minute or so - if it freezes, you need to connect a wired network and re-boot.
Start the installation process once you have it booted from live usb.
Use the 'advanced' option with gparted to partition your disk, if you are starting from scratch. I set up 4 partitions as follows:
- a boot partition of 250Mb
- a root partition of 25Gb
- a swap partition (at the end) of 8Gb
- a home partition of the rest (about 260Gb)
Finish the install and re-boot, using the ethernet connection if you had a frozen cursor earlier.
Go top this page and follow the instructions for power management http://ubuntuforums.org/showthread.php?t=1811178 and the rest is useful too.

Welcome to a fast and easy to use netbook!
I've been using an Acer AO722 for nearly two years, and I have tested lots of distros. Here are some findings:
- avoid any distro with KDE, for they overload the system. CPU temperature gets very high!
- Unity and Gnome are Ok, everything works fine (as long as you fix the boot order - see above answers), but they consume too much memory.
- XFCE distros work fine, too, with very low memory consume. I've been using Xubuntu 12.4 for more than a year, and it's on top of my GRUB order! The problem with the XFCE distros is the sound issue(s). I've managed to fix it, but I can't remember how (sorry)! It has to do with some lines in the Configuration Editor.
- LXDE distros have no sound at all, and i couldn't find a way to fix it (I've tryed Lubuntu and Peppermint).
- Bodhi Linux is great and works fine, after configuring the workspace.
- Puppy Linux Slako is another great distro. Everything working fine, but wireless configuration can be tricky.
My final choices are Xubuntu and Linux Mint.
