Even though the audio needs some work, I thought you laid out the video well and explained what is important instead of rambling on. I love Ubuntu and I am looking to get a Surface Pro 2 and you answered most of my questions. I also love MS Office since I have been using it in the days of 3.5 Floppy disks. I have been able to get it to work in Mint but not Lubuntu. Thank you for the excellent video. Rock on!
You should consider using Mypaint for hand note taking. It is cross platform, has a lot of options, and with some time invested because of the keyboard accelerators you can really do work quickly – it is also pressure sensitive.
