WTF, I thought there's only two types of Zenbooks. The original first gen, and the upcoming Zenbook Prime (in 11.6" and 13" respectively). Is there a '5th' model in their lineup?
LOL @ Mikroft. I bought the Acer based on how many RFD guys jumped on the wagon. I picked up one just for kicks and to be honest, it has exceeded all of my expectations as a beater laptop. The keys have not faded, has a very good keyboard (much better than the new Dells IMHO), batt still holds 7+ hrs with my M4 SSD, and the display is OK for a little Lightroom 4 action (I had it collaborated with my funky monkey, or spidermunky thing).
The new Samsung Series 5 is quite tempting too (i5 + intel 4000 + 500gb + 24gb SSD cache; ram + hd can be easily replaced). It goes on sale for $799 in the US soon. It's considered an Ultrabook (only slightly thicker than the series 9) and has a full aluminum chassis.
