I currently have a Amazon Kindle Fire reader/tablet.
I had a xoom but it got stolen a couple months later leaving it in my gyms locker on accident. Hopefully I can buy another soon cause I really loved it, it was fast and could certainly browse the web faster compared to the Acer Tablet, and the Xiboard
I got the Sony tablet S. Its amazing, perfect for all my uses. And its confirmed to be getting 4.0 so I am so pleased to have it. I have had the blackberry playbook (very nice but not many apps), xoom(it was just ok), asus iconia a500(decent imo)... But the tab S is without a doubt the best imo, and it has PS games which makes it even more win.
