We don't get much of a choice here in Russia, really only the Iconia, Xoom & the Samsung Galaxy, so far this Iconia is my favourite. |

I got the Galaxy Tab over on Friday from a local BestBuy apparent they are not suppose to sell it until Monday. The screen has very wide viewing angle, I looked at the Ipad2 before I looked at the Galaxy Tab, and I couldn't tell the difference based on memory, but I'm sure Galaxy Tab is better. Though the screen is better than the Xoom which I also own. |
