I've just taken delivery of this new Acer Aspire One (Amazon delivery took 5 days).
Out of the box it looks great, it is light, the build quality looks and feels very good and the screen opens smoothly. It came with 80% battery life already which is handy if you don't have electricity to hand immediately.
I booted it up and went through a simple 4 step setup process (language, country, time, password) which took about 3 minutes. Then the OS booted. It is very user friendly with big links on the opening screen for Web, Mail, Photos, Video, Preferences, Documents etc.
There is no link to "Wireless" or "Networks" which would be handy, but there is an icon in the botton right. You click on that icon and it shows you all the wireless networks within range. I connected to my home wifi without any difficulty (though I don't use WPA or WEP security - I am a believer that wifi should be shared and free!).
The laptop is for my mother and she will have no trouble using it. It is a replacement for an Asus EEE that I bought her 4 months ago. The EEE was beautiful and cool, but it was temperamental in connecting to wireless networks. That's a major flaw.
I would strongly recommend the Acer Aspire One over the EEE. It is cheaper, just as cool, just as easy to use and it does not have wireless network difficulties. Top marks Acer and welcome to the mini-laptop market. Competition is great.
