Optimistic that Microsoft is headed in the right direction.
I have similar work demands, and have arrived at the same conclusion. I spend time at the office, travel on the plane where I use my iPad mini for movies, music, and web browsing. The Macbook Pro is my power laptop for traveling, and I use it for PowerPoint presentations. The Galaxy Note 2 takes care of my mobile needs (Calendar, email, tasks, notes, okay games too).
What I wish for is a Surface Pro that looks like the RT version, has good battery life, can run iTunes, Office software (it already does), integrates my Google ecosystem, so I can simplify my life. I want one device I can work and travel with for media consumption, and perhaps a decent smart phone (even a BB10). That's it!
Perhaps battery technology, integrated touch-friendly software, more apps, and a special focus on usability vs utility will get me to switch over.
p.s. My work and home desktops are pre-Windows 8 PCs.
