I've had the Acer Ferrari One for a couple of weeks and think it's excellent. If you can get over the garish design (I actually love it) it's a great little machine. Build quality and finish is excellent, very nippy and feels much more laptop like than netbook in use if that makes any sense. I would say only downside is it does seem to run quite hot and the fan is on a lot although not that noisy and battery life could be better. I paid £305 for it refurbished.
I use it so much I'm hardly on the desktop anymore so that's a good indicator for me..
Just re-reading your post though are you sure a netbook form is what you want ? Unless you need the ultraportability wouldn't a normal laptop be a better bet >
