It only seems to be hinted at w/ the speculation thus far, but am I to assume that if I pony up the $s for the mobile carrier version upon it's release, I can pay for 1 month of data coverage, cancel it on day 29, and voila, I've now got a Wi-Fi Xoom in perpetuity? That's not the worst of situations, I don't suppose, but seems iffy to me...can someone that knows more about it chime in? I would think if that's the case, then having the 3G/4G model might be an advantage, especially if someone later decides they want to add a data plan back on it (like, say a year, when the LTE is fully implemented)...you couldn't change your mind w/ a Wi-Fi version w/o trading it in...
