After owning the Nexus S 4G since June 2011, I can rest assured that I will not NEED another phone until my upgrade is due. That is, barring a major catastrophic accident, I am satisfied with the phone.

I previously owned a Palm Pre on Sprint, and I was unable to make calls in the last weeks before I upgraded. The simplicity of the Nexus S is what attracted me. Rooting the phone was as simple as finding the correct forum on XDA, downloading a one-click-root, and connecting the phone. Since then, I have run a handful of custom ROMs on my phone and I'm currently previewing Ice Cream Sandwich via Peter Alfonso's new ROM. Even when I revert to the stock Gingerbread ROM, I am not disappointed. The phone is very capable although it doesn't sport a dual-core processor and has only 512MB of RAM. Everything just works. Whether you're a novice, enthusiast, or expert, you can appreciate when devices just work out of the box. It just goes to show that lightweight optimized software is priority number one.
