The speakers in the Aspire One are nothing short of awesome. It’s pretty annoying to have to strain to hear movie dialog on the crappy speakers built in to my £600 laptop, but the Aspire One not only has oodles of volume, but a better bass frequency response, at least when it’s sitting on something solid like a table.
There are 3 USB slots, so adding a mouse, printer, and external drive without a USB hub is no problem. The only real letdown is the dreadful battery life. If I turn down the brightness, switch off Wi-Fi, and use non-CPU intensive applications, I can squeeze a little over 2.5 hours between visits to a power point. The other compromises Acer have made are a lack of built in Bluetooth (you’ll need a tiny USB adapter) and an optical drive (you can make a bootable USB stick from the restore disk using another machine).
