Philip Greenspun is asking what is
Best 13 inch windows laptop?
Jeff Atwood has the answer:
Lenovo Yoga 13 - Buy Lenovo Yoga 13 Online and View the IdeaPad Features | Lenovo | (US)
Before this he suggested
The Last PC Laptop,
ASUS Zenbook UX32VD-DB71 13.3-Inch Ultrabook
,
but apparently that was not not universal enough...
Or convertible does not count as a laptop, so he can get them both :)
In fact, a compromise may be ASUS VivoBook S400CA-DH51T 14.1-Inch Touch Ultrabook
with 24GB SSD/ 500 GB HD combo, and touchscreen, for less than $700.
There will be many more touchscreen laptops soon, since they are in demand...
