I don't have a true Ultrabook but I do have a Sony Vaio Z with a 13.3" 1920x1080 screen in it. I run it full resolution in Windows 7, with everything scaled down to standard size. Is everything very small? Yes. But when I'm sitting in front of it it's not much different than being a couple feet from a monitor and it truly gives me usable space. It's my travel machine as I am on the road a lot, and since I've had it coding in a hotel room is finally productive for me.

Why do you say to be wary of the 32VD? I was literally just about to buy one.

My understanding is that the thickness comes from the fact that the body isn't a single piece of metal, so you can swap out the RAM and HDD (unlike the 31A and 21A). Also, apparently you can repartition the SSD that's used as an OS cache into a separate drive reasonably easily.

As much as I'd prefer the formfactor of the 21A, the ability to upgrade to 8GB of RAM is too big of a selling point to pass up on the 32VD.

Yeah, it's just the difference isn't clear from the model name.

The 32VD is bigger/thicker than the 31 models and has a hybrid HD(24GB flash) rather than full SSD. It's got a dedicated graphics so I guess it's just targeted towards a different market.

Same! I'm curious too
