smacman, member on our message forum, has a good summary of the Acer Aspire One.

“The build quality is very good in my opinion. One of the reasons I held off from buying the EEE PC was it’s toy like flimsy feel. The Aspire One feels more like a real laptop yet retains the ultra portable size and weight. I also have no complaints about the keyboard. It is obviously not as easy to type on as a full size, but in the short time I have had with it, I am getting quite used to typing on it. The display is bright with good contrast. The only thing I am noticing is slight color inaccuracy when I view my photos on it. There is a very slight blue/green tint to it which is only noticeable when I view photos. I didn’t buy it for image editing so it does not really bother me.

After powering it up, the first thing I noticed was how quickly it boots up. Within 5 seconds I was in a configuration screen setting my locale and time zone, etc. After this was set, one reboot (aprox. 15 seconds) and I was up and running on the Linpus desktop. They have really made the interface bulletproof in the sense that I don’t think you could bugger this machine up if you tried. Settings are limited to very basic things (trackpad sensitivity, volume, date/time, etc.). There is no facility for adding/removing programs so you get what you get. Firefox 2.0.0.14, Openoffice 2.3, a media player, some games, a mail client (very basic), a messenger program (supports MSN, Googletalk, Yahoo, and AIM). I would have liked to see Skype preinstalled, as well as a better mail client like Mozilla Thunderbird. Considering most people will by this machine for basic tasks like document viewing, web surfing, and email, I think the software is adequate. I wish the OS could be customized a bit more. It would have been nice to have an advanced mode for users who like to tinker a bit. I am hoping to install Ubuntu on it soon.”
