When ASUS released the EEE only one model was initially available. ASUS, probably drunk with the success of the EEE, released many additional models in the following months, which only led to growing confusion among consumers. At about the same time Acer stepped into the netbook market and released the Aspire One in form of a single model with just a few configuration options. It was one of the many reasons why the AA1 became the #1 netbook. Now, as you can see in the pictures below, Acer is about to release yet another model of the Aspire One. There might be a pattern here.

It looks very much like the just released D150, so you probably wouldn't even notice that it's a new model. The most noteable changes are a completely different motherboard layout, evident in the rearrangement of all ports, and a few minor design improvements. It's also slimmer with a height of only 26 millimeters. You can use the dimensions and pictures of the D150 posted in a previous post for comparison. The technical specifications remain unchanged. And despite being what appears to be only a minor revision Acer will increase the model number to D250 for the HDD configuration.
