Do not see the need to have a device that I have to go and install a ton of different add-ons to accomplish what I can do today with my WP8 and Surface RT.
Yes you may get some differnt features using these add-ons. But everything listed above can be done with a Windows Phone and Surface RT and having Skydrive sync to my computer.
No need to convert data from one format to another with my office documents.
I use OneNote everyday for all my note taking and it syncs to my skydrive. Only thing I had to do was have Skydrive installed on my Windows 7 computer.
OneNote, Office Docs, all sync between my devices.
Once we upgrade our SharePoint Server it will add even more flexability.
