So I'm considering getting this in the 80 250GB version. I was looking on the Amazon site and there are some reviews that talk about it being glitchy and the screen being unresponsive. Have any of you, who have it, encountered this? Those of you who do have it, what do you think? Has the ICS update, mentioned in a different thread, happened yet? Or any word of it? I really like the looks of it, and it seems (from the specs) to be a nice tablet.
