Yes, and not just on CR, but most forums I'm on.
I've had T-Mo since 2002 and I've never wanted to switch. They have the best customer service, the best price, the best attitude towards customer satisfaction and doesn't want to lock your phone down so that they can have total control over you, and works the best out of other any of the other carriers when it comes to traveling to other countries. People like to say it has crappy coverage, but it's just not true. Yes, it's not like Verizon's coverage, but like you said, you don't give a shit about reception in Yosemite.
I just recently switched to their $50/m plan and it's great. Unlimited voice and text with 1GB of data. It's perfect for someone that's always on wifi, and even if you go over, you wont get charged overages. your speed just gets throttled down. Most popular music streaming services don't even count towards your data usage.
There is rumor that Google will be launching their own service provider this year which will be running on T-Mo AND Sprints network. I might consider switching to that depending what the price and stipulations are.
Oh and the Verizon Edge plan is just a copy of what T-Mo has, where you can pay your phone off monthly. They also just introduced SCORE, which is basically the opposite. You pay $5 a month extra to join SCORE and then after 6 months you get a free entry level smart phone or after 12 months you get a big discount on all smartphones.
