I don't have an EeePC so I am probably not the best to compare, but at the $300 price point the Aspire One looks to smoke it. I can't imagine it has better build quality, the Aspire One is really solid. Here's the EeePC I found for the same price:

It has a 7" screen, 800MHz Celeron, 4GB SSD, etc. The specs aren't even close. I think screen is the most important, there is a huge difference between the 1024x600 that the Aspire One has and the 800x480 of the EeePC.

No wireless. Less space than a nomad...

Just kidding.

I can't comment on how it compares, but it is awesome.

I have one of the new 6 cell ones. I get 5 hours of battery life actually doing stuff on it (multiple programs open, etc)

For $300-ish I think it totally blows away the competition as well. I feel almost stupid that I just bought mine from Amazon now for 399, but it is worth it

I have a 7'' Asus EEE and I have to say that the small keyboard and small screen really kills the experience.

I think that I'd much rather get the Asus S101 even though it's more than double the price.

It's a 10'' screen and thin like the Mac Air. But at $700, that's still quite the steal.

As a caveat, I just bought the new Macbook and I'm loving it. I think that this thing is really portable enough for me to take anywhere, and yet powerful enough for me to use as a desktop replacement. It's really the best value for the price. (Plus, for lack of a better way to describe it, OS X = ownage)

I just got the new macbook too! Its so frickin solid. The only thing that makes me mad is that they don't have s-video adapters anymore...lame.
