Is Acer going the way of ASUS by releasing countless iterations of their netbook? Probably not, but there will be at least one additional model as shown in the pictures below.

You'll notice it is thinner than current models, which indicates a SSD only model. Another clue is the return of the SD Expansion slot. The software based funtionality of it was only used in Linux, so unlike with the just released 10.1" AA1 a Linux configuration might be available again. The only thing that indicates otherwise is the Windows key. Linux models have a home key with a little house icon instead. It'll likely be available in both configurations just like the first generation AA1.

The awkward position of the VGA and the RJ45 port shows that Acer specifically designed the motherboard towards a slim design. Overall it has a more barebones and lightweight look to it, compared to previous models, which will hopefully be accompanied by a low price.
