I have been thinking of getting a tablet to use at my work conventions. This would be use to look up info on the net, prices and things like that. My phone is a little too small of a screen and I don't want to be lugging around one of my laptops. I have a hotspot in my phone so I don't need a tablet with internet, just a wifi and I can connect to my phone. I have a HTC Evo phone so I use andriod currently. What 's the difference in the Andriod tablets and the Ipad's?
