Change O/S on slide?
So when I'm leaning back on the couch reading a Reg article and then I see a comment that I just have to reply to, what happens when I put the tablet on the coffee table and slide the screen up so I can type properly? Does it flick back into Windows 7, where I can't access the web browser I was running under Android, meaning I need to fire up Chrome on W7 and browse back to the same page? Seems painful.
I see the change of orientation as something you do after you start a task and decide you'd be more comfortable reading the document you have open if you were on the couch or whatever. It should be an organic, quick thing that happens when you decide to change the way you're working. It shouldn't mean stopping and thinking before you open a browser or document "where am I planning on working on this, and should I close the keyboard *before* I start?". One operating system is the correct number here methinks.
