I'm jumping ship from AT&T (I've got it all planned out, trust me) and getting the G2X, but the Sensation definitely has me thinking. The "Pyramid" official release info was something I was holding out for before I pulled the trigger.
LG makes some **** dumbphones for AT&T, but this Optimus 2X is the first high-end phone from them that's really catching my eye. The four-inch form factor appeals more to me than 4.3". I ditched my Inspire for the Atrix for that very reason. One-handed use is much better on the narrower phones, but the 4.3" 16:9 screen on the Sensation looks like it would work well.
People want to talk about software upgrades and whatnot, and how HTC updates their older phones.... I thought we were on an Android forum? You people really wait for official updates? I think not. Software doesn't mean anything, it's all about the hardware. HTC's track record with software doesn't mean anything to me, it's their track record with hardware. Everyone touts their HW as being great, but in reality, their earpieces, loud speakers, and battery life SUCK. I've owned the Desire, Desire Z, Inspire 4G, Nexus One, HD2, and they're all subpar. I don't know why I keep trying, but I'm breaking the cycle with this one.
LG G2X, here I come.
