I had my Galaxy Tab for 4 days and returned it for a 32GB Nexus 7.
After taking it with me a few places and barely getting a wifi signal compared to my iPhone and a friends Nexus 7, I figured that would be the best thing to do. Even though I ordered it online through Wal Mart, I was able to return it to the nearby location and they had one Nexus left. It is charging up right now and I look forward to getting better acquainted with it this weekend.
