Small Windows 8 convertibles with digitizer

I'm looking for a good Windows 8 convertible that have stylus support/digitizer. My contenders so far:

- Surface Pro 2.
Basically an upgraded Surface Pro, so it will have great build quality. The con is the price for the full package (adding keyboard).

- Dell Venue 8 pro
Cheap, comes with Office. Cons are it's running Atom, and who knows what other corners that Dell cut.

- Sony Vaio Tap 11.
Seems like the best middle ground. Office is not included though. Also, I don't know if 11" would be "too big" or not.

Any other suggestions? No Android tablets please as I need Office. Also, I prefer newer chipsets (Haswell/Baytrail).
