After reading many reports on the internet about installing Windows 7 on an 8GB Acer Aspire One, I decided to give it a go tonight. Reports on the web said that it would not work on an 8GB SSD without compressing the disk. This would take somewhere between 24 and 48 hours!!!
Anyway, I pressed ahead and managed to transfer my Windows 7 RC onto a bootbable USB drive without too much hassle, though it took over 30 minutes to do so. Install took about 2.5 hours, give or take a few minutes. There was no need for disk compression at all. It would seem that the previous beta installs of Windows 7 are slightly larger than the current Release Candidate.
Once installed, I was left with just over 800MB. I uninstalled a few unnecessary a applications and free space grew to just under 1GB of space. Even though installation took quite a long time, I was impressed when finished as everything worked on first boot.
I put an 8GB SD card for more storage and installed portableapps versions of Firefox, VLC, and Sumatra PDF. I also installed Clamwin AV. Windows 7 had no problems connecting to my home network and browsing my home network was nice and quick.
Once I was happy with my setup, I decided to play around. I started up Firefox and browsed to some of my favourite sites. I also used VLC to browse my network and play back some media files. Video playback, whilst not choppy, slowed down on multiple occasions. As I plan on using my AA1 for watching movies on the go, I figured this would really annoy me!
My Acer Aspire One has the following specs: 1.6 GHz Intel Atom, 8GB SSD, 1GB Ram. It is entirely possible that an Aspire One with more Ram (I believe the limit is 1.5GB) could happily run Windows 7
So, to sum up:
