For the desktop: it is faster for most things, takes better advantage of hardware, has built in VHD and VCD mounting (which works wonderfully!), more secure, better networking (homegroups work properly, never got it to work right in win7), move from home to pro which moves my max ram from 16GB to 32GB (mobo cap, not OS cap), and more seamless content and social media use.
For the netbooks: runs smother, less ram used by OS, more than 1 hour of extra battery life (4 hours to 5.5 hours on my use), and the content and social media stuff that is 'baked in'.
For the wife's PC: she likes the new start menu because it is more useful and easier to find stuff than the win7 start menu. Personally I disagree on that point, but that is her opinion.
There are plenty of changes in win8 from win7 other than the superficial interface changes. It really is a better OS. Not revolutionary... but definitely $40 better.
