Trying to decide between the Acer Aspire One with an 8.9 inch display and a model with a 10.1 inch screen? Portable Monkey has put together an excellent guide that can help you choose.

The most obvious differences are that the 10.1 inch Acer Aspire One AOD150 is larger than the 8.9 inch AOA150. Bot computers come with 1GB of RAM, a 160GB hard drive, 802.11b/g WiFI, and Windows XP Home Edition. As reviewed, these netbooks have 3 cell batteries. But there are a number of subtle differences:

• The 10.1 inch model has a louder speaker
• The touchpad on the 10.1 inch model is a bit larger and there’s a single button below the touchpad instead of on the left and right sides
• The 10.1 inch model has  brushed metal casing instead of plastic and does a better job of hiding any fingerprint marks
• The larger model gets better battery life

For some baffling reason, the keyboard on the 10.1 inch model is identical to the 8.9 inch keyboard. Even though the computer chassis is a bit wider, the keyboard is not.
