I dumped an evo and an epic and picked up two g2's. My wife was heartbroken to give up her epic, but I will say the g2 kicks the evo's *** in real world performance. The display is much improved as well. Its no super amoled, but very crisp with great colors.
I lost my Nexus One in a cab while visiting family in NYC during the Christmas holiday (Engraved Garry J Murray on back) Anyway, I figured to make the most of my misfortune by replacing it with a Nexus S "upgrade" I went into Best Buy and had my first up close, hands on with the device and changed my mind. It is a light, plastic, cheap feeling phone. No HSPA+ (4G), NO SD memory, No deal!. It just reminded me of my sister's galaxy S. I instead went to T-mobile and picked up the finely designed, well crafted HTC G2. A beautiful phone that more closely resembles the Nexus One than the Nexus S does. Feature rich, wi-fi calling, mobile hotspot, 4G, physical keyboard, can expand to 32 GB. Best decision I could have made. I really WANTED to like the Nexus S, it just fell short in my opinion.
Am giving up my Nokia E71. I love the build quality of the phone, but I am so tired of the Symbian OS. Coming from the original Palm OS, it's nice to have a touchscreen again, and as my first Android phone, I spent 3 days mucking with things before I finally dropped in the SIM card. I really wanted a physical keyboard, and so far, I am liking the transition.
What I don't like is the short battery life. I did condition the battery when the phone arrived, and have disabled wifi, gps and background sync. But wow, I wish there was a stronger battery out there!
