I ordered a Transformer Prime last year, but had my preorder canceled and chose to not reorder. But I finally gave into the tablet market (after using a borrowed iPad for a long time), and got a Nexus 7 a bit ago.
I'm still feeling it out. But so far, I love it. The size does have its drawbacks, but it feels great in the hand. The iPad is better for browsing, but the Nexus just feels better on you. The buttons are a bit too flush for my liking - I still **** up the power and volume buttons - but that's a minor complaint.
But the product itself is great. I can't put it down.
