Difference between netbook and normal NIS versions?

Hi All,

 

I'm curious to know what is the difference between the 'netbook' version of NIS 11 and the 'normal' NIS 11? The reason being I have a three license version of NIS two of which are used on our two home desktops and last week I installed the third licensed NIS on my other son's laptop (Netbook). As far as I can tell, it sits very nicely on there and everything appears to be running as it should be. I checked the 'tasks' window and everything seems to be working normally. I now see the odd thread on here referring to the 'netbook' version and wondered what is the difference!
