Acer aspire one (I think its around 9" of screen).
My proper laptop failed and I bought this as a cheap quick carry around while it was being repaired. Its been great! I expected slow, I got fast.
I run AVG antivirus on it as McCaffee that it comes with seems to cause hesitation. I am pleased how fast the netbook is generally. I have even run photoshop CS1 batch jobs on it. CS2 wont work due to Adobe programming in some screen size restriction.
You can get bigger batteries from Amzon to make it run 6 hours plus without mains connection, I have found mine to be sucessful.
I find it handy to use close up and its great for proping on your chest lying down to watch films etc (I have an external drive) I am experimenting with copying films to the hard drive or large memory sticks. Its screen is harder to see on a table than a normal laptop, but there are other compensations and also, you can plug them into a freestanding monitor if you need a big picture.
The best way of describing it is 'cuddly' as you put it places and take it places its just too difficult to use a full size laptop in. I know 2 other people with netbooks and they both think they are great too.
If you manage to get one from John Lewis, there is a 2 year free warrentee on most of thier machines.
