i have come to this question before, actually u need to know what is your purpose of purchasing tablet...
looking at specs, i think SGT had more advantages compared to Ipad.... Ipad camera is a less than 1 megapixel, no external memory slot, etc2...
I'm not very familiar with Android, but iOS is very much stable, you can have many opened apps and the ipad still give u wonders...
i think the best thing in ipad is the applications, especially apps in HD, extraordinary graphic and a lot of usefullness for every type of ppl....
i chose ipad because i want to share with my kids the best education aid tools with thousand of apps to make them enjoy the process of learning... as well as for me to play games sometimes
so back to the 1st q, what is your purpose....
