I switched from a VZW Nexus to a GSM one, with the T-Mobile pre-paid plan ($30/month). Could not be happier.
My leaving Verizon had little to do with the update... but more like a trend of degradation in their consumer friendliness.
- Imminent loss of unlimited data
- Constant addition of new fees
- Poor customer service (in my case)
- Poor phone selection, bloated phones, lack of updates, etc
The advantages that I now receive:
- Literally saving $50/month, $600/year on my cellphone plan
- Updates straight from Google
- No contract whatsoever (if T-Mobile starts sucking more, I can just pop in a new SIM card and carry on
- Better resale value (since its a GSM phone)
- International support
- 5GB of unthrottled data with no overages, versus 2GB on Verizon
The disadvantages
- Loss of LTE (which is also somewhat of an advantage considering the battery drain was horrible on the VZW Nexus but great on my GSM one)
- Worse coverage in some rural areas
I think so long as there is sufficient coverage in the area where you will be using your phone, its almost insane not to go the pre-paid GSM route. I'm absolutely thrilled. I think for me the single biggest improvement is not being under contract. Knowing that I can jump around month to month and really shop for the best carrier, rather than being beholden to one.
