If I go the HD route (thinking of Note 2), I'll do retail to keep ULD. If a Maxx comes out later, I'll be upset. However, if the "non" maxx with 2550 isn't enough per reviews, then I won't buy it anyway.
My thoughts are that if you bought the razr with a non removable battery and after 14 days found out it wasn't enough for you, you should have returned it. Then when Maxx comes out, you really cannot be too mad like VZW screwed you. You, all the way to the day before the maxx announcement, had a good phone that you thought was worthy of your money. Then a maxx comes out and your mad because your battery life sucks? Should have returned it in the 14day window.
Well, sure, I'd be upset, who wouldn't; but not fully angry.
So that I don't get screwed by a mysterious maxx HD coming out. I'll do retail. If I then would like more than 2550, I'll sell for a loss and buy a maxx.
