It should work great on a netbook. If it has memory; slacko will run blistering fast right from the USB.
This guy tested it on Acer an Aspire One D255.
So far I am quite happy with it - I have it attached to my keys which I usually have in my pocket - so when a discussion about Linux arises; the demo is never far away.
If the box can boot from USB it will work.
Uefi "secure boot" might be a problem since it reduces the capabilities of the HW to "only for Windows 8";
Knopix seems to have fixed that.
It is possible to boot puppy too -but it is made so difficult that it makes Microsoft smile.....
Anyway most people do not have a Windows 8 box - and my advise would be to stay away from them since it locks you down - even if you should like Windows 8.
There must be a way for Windows 8 to boot securely without excluding (or making it ridiculously difficult) other OS's - since MS says "my way or the highway" - take the highway
Because I do not even attempt to demonstrate Puppy Linux on those boxes - so those poor souls are deprived of that information/education.
That dongle is solid and I particularly like that the connection is covered with rubber when it is not used. That means that it does not "adopt" the crumbles in my pocket.
