I finally got to buy a small 10.1 in Acer Aspire One 521 Netbook.
Got rid of the Windows 7 Starter edition on it plus all the Crap / Trial / bloatware that usually gets pre-installed on Store purchased machines (The AMD V105 processor has a bit more "oompf" than the usual Intel Atom processors that Netbooks are generally fitted with) and proceeded with a Windows Professional install.
Machine works FINE with Windows Professional Windows 7 x-86 -- although remember to load the BROADCOM Wireless LAN driver
BEFORE wiping the old software off your disk or you will have trouble connecting to the Internet.
Running Office 2010 , Photoshop CS5 and IE9 on it. All work fine.
While running photoshop on a 1GB netbook is not normally good to do for long periods it DOES work.
Very happy with this EXTREMLY portable netbook -- only cost me around 220 EUR too.
Its just the ticket for taking on Planes, and trains these days and fits easily into a backpack with your other hand luggage items.
I'd definitely recommend this type of computer for travellers -- of coursse it wont replace a fully specced Laptop or desktop but can be used when you don't need to run loads of VM's etc on a machine.
