This deal is not really compelling when you consider how reviews mention the awkward feel when the laptop is flipped. It's only 5.5 hours of battery life as well. This doesn't give that "I'm glad I bought this when it was on sale" feeling.
I don't use mine in tablet mode. I do, however, flip the screen to face me and use the keyboard as a stand. It's much more comfortable that way anyway.
But yes, it's a heavy tablet. You're not going to be holding this thing over your head for an extended period of time. But that hinge is something that needs to be on every laptop going forward, because it's so versatile.
