Just to lay the record straight, I am not in the pay of Canonical, nor am I a Total Ubuntu Fanboi. And here to prove it is a blog post detailing problems [gasp!] with Ubuntu linux on the Acer One A110AB Netbook.
Firstly, there is an issue with the sound -- I can't get the internal mic to work, which is a shame as all I can do on Skype is wave to my brother in Belfast. I can hear him but he can't hear me :(
Secondly, and more frustratingly, is the fact that the SD cards aren't recognised unless you put them in before booting. Obviously not very practical. I have inadvertently found the clunkiest workaround on the planet -- I have a USB stick SD adaptor (mine is from integral but I think they're ten a penny), and as the USB bus is working fine, we are all happy in a sticky-out, clunky sort of way.
I'm sure it won't be long before these issues are addressed, particularly considering the amount of interest the Acer Aspire One is receiving. This is purely anecdotal interest (a man on the street had spied me using mine in a cafe and asked me what I thought). I really do like them, apart from the buttons on the side of the trackpad. And at 199 a pop from Dixons/PC World, it would almost be churlish to complain.
