Yes there are a lot of downfalls to the Nexus IMO. I hope the GSM radio isn't junk like the radios on CDMA Samsungs. I have had a handful of bad CDMA Samsung devices.
Being able to switch between GSM every month for the best price, updates straight from Google, no carrier bloat or BS, and the money savings on cell plan, and more early termination fees or contracts makes it worth it to me to switch. I am sacrificing unlimited 4g LTE, but Att HSPA+ is pretty fast where I live, and I only get very slow VZW 3g in my town anyways.
