It's also worth bearing in mind that Windows 7 Starter does have limitations not present in other versions of Windows 7. For example, it's missing the built-in encryption and the Windows XP Virtualisation Mode found in Windows 7 Professional.
When a second display is connected to the VGA port you can only mirror the contents of the Aspire's screen onto the external display, not show more windows.

Aside from the dual operating systems, the Aspire One is otherwise very similar to other netbooks, both from Acer and from other manufacturers. It's equipped with 1GB of RAM and a dual-core Intel Atom N550 processor. It's fast enough for simple, everyday tasks, although the limited amount of memory does make using more than one or two applications at once sluggish. Adding more RAM is trickier than it is with some other netbooks, as you have to remove the entire bottom plate to access the memory slots instead of just a single access hatch.
