...I think the tablet is powerful in the sense that you can get 90%+ of your work done 100% of the time...

I still live and work by that % thought. I recently brought my laptop home a few times during the week. With some extra work piling up, I thought it'd be a good idea to just keep working where I left off even though I wasn't in the office. It was awful.
Lugging the bag around wasn't worth it - I eventually used a combination of Dropbox and Google Drive, along with SharePoint so that I wouldn't have to haul the bag and laptop around. Using the Reminders app, coupled with Penultimate for note taking, I was soon back to my non-lugging around ways.
My next step is to figure out how to do the same within the office.
