Onenote is not included, though you can download a free version. It used to be called Onenote MX and you can google the name and see how it compares to the desktop version. I have Onenote 2013 and the MX version and prefer MX.
No OneNote but it does include several Samsung Apps. You have to remember this is an Intel Atom system running a full 32 bit version of Windows 8 and only 64gb of drive space. It does have a trial copy of Office 10. Hope this helps.
Nothing notable. You can download the one note app buts not as robust as the full version. This device really isn't a good option for running the full windows 8 - it moves slow and mine had several glitches right out of the box. Went with the Surface Pro 128gb and love it so far.
I get Norton Internet Security 2 month trial edition and some free software with SW-Update (Samsung software/driver update), no MS Office. It's windows8 not win8 RT. So it's not including Office(Word/Excel/Onenote...)
