I'm not sure about the "can't use it in bed" argument. I've had iPad 1st gen, 3 Android tablets, an Asus T100, and now an original Surface... I could/can use all of them equally well in bed. I also use my original Surface more as a tablet (usually in bed) than I do as a laptop, though when I travel it is used 50/50 and makes an excellent single-device for travel. Now, my usage of the Surface Pro is probably 75% browser, 15% Outlook 2013, and 10% Metro Apps... my iPad/Android usage was probably closer to 50% browser and 50% apps. When traveling, the Outlook/Office usage probably jumps to 40% while the browser usage drops to 50% and the app usage stays right around 10%.

So far my only real complaint in terms of missing Windows Metro apps is Pulse News Reader, but News Bento has been an adequate substitute... and I got my Asus T100 about 1-week after LinkedIn acquired Pulse and pulled the Pulse app, otherwise that wouldn't even be a complaint for me.
