I hate the same ole rehashed Android vs Apple (Ipad Killer? Android sucks!) threads that pop up every forum I go to. Why not own both and enjoy what both has to offer. I have an android phone and absolutely love it, but I have an Ipad that I absolutely love as well. I get the best of both worlds. Both have their advantages and disadvantages.
Now back to the original question. I have owned both but returned the tab for an Ipad, why? Because I have an android phone already and to be honest it wasnt much more of a different experience than owning any other android device, just bigger. I wanted a totally new experience and wanted to take advantage of all the optimized apps that are specifically made for Apple. Truthfully just about every retailer, newspaper, weather, etc has an app for ipad/iphone. It is slowly but surely turning for Android, but for now the Tab is no Ipad killer JMHO. When on the tab I was just longing for more space in seemed in every operation I wanted to do on my tab, from games, apps, browsing, etc. 7in to small when you already have a phone that is 4.3in.
