I recently purchased an Acer Aspire One (6 cell version) and ended up spending a surprising amount of time looking for a case for it before tripping across this one. I am happy to report that it is a perfect fit. Moreover, it has a full size external zipper pocket that is roomy enough to hold both the Samsung external optical drive I purchased for the machine and the battery charger without adding any appreciable bulk. The detachable shoulder strap is the option I particularly wanted since I often do not have a free hand when traveling. The only mystery is why Amazon does not list this case among the suggested cases for the ACER machine since it is an excellent choice.
