On the Acer 532h netbooks, I've run into two issues I haven't cared enough to fix just yet: The SDHC reader didn't work at all under the last build of Ubuntu, and the mouse was problematic. The multi-touch trackpad caused frequent errors when using whatever the default mouse driver was, but there was a fix out there somewhere. Upgraded to the current version a week or three prior to its release, but that caused the mouse to become completely unresponsive. Been too busy to deal with it since, but beware: These particualar etbooks aren't exactly problem-free.
