Primary negs with the yoga:
-SINGLE CHANNEL DDR (memory bandwidth neutered)
-Fan always runs
-Unknown hinge longevity
-13.3" --- large for a tablet (play with it first in the store)
-low thermal throttling
I've had Yoga for a couple of month.
Hinges are the same kind as on T line - steel; they are absolutely indestructible.
Single channel vs Dual is an old debate: tests might show maybe 5% performance difference but in real life it is close to zero.
Tablet feature is more of a novelty. I turn on the tablet mode when I give it to kids to play games.
