I'm in your exact position. Aging Nexus One that I plan on replacing, using t-mobile. LTE isn't an issue for me for a while, as I don't plan on giving my money to either Verizon or AT&T in the near future. My storage concerns were cleared up when I realized I have ~5gb free on my current 16gb sd card. Would both of those things be nice? Sure, but I doubt I will actually miss them.
