For me it wasn't about love and hate it was fear and loathing. I feared that I'd not be able to afford a cell phone, and I loathed the reason why. Cell phones are damn handy. Almost nobody sells a phone anymore, it's all about smart phones. And they're expensive when adding up the monthly charges. I want a dumb phone. I don't use all the features of a smart phone, so why pay smart phone prices? That's dumb. I had AT&T ever since I bought my RAZR outright because AT&T was the first carrier I got who gave me a phone that didn't work. I really like my RAZR, it just works. As a phone. I tried explaining this all to AT&T and they wanted nothing to do with me unless I handed over spendy ducats every month in usage fees for things I don't use. Why should they care, all other carriers charged about the same if you wanted just a phone. Except T-Mobile. I saved $20 a month by shutting off internet, texting, and even got my RAZR to work with their service after going round and round with AT&T about it being my phone bought much, much longer than 2 years ago and, no, I'm not interested in any bundle or new phone just unlock mine thank you.
If you want to talk about my love/hate with AT&T I'd have to talk about how Comcast won't do (cable upstairs wonky) for TV or internet and AT&T is charging about the same, bundled or otherwise, with Comcast but again, $20 more per month than a local DSL provider than just now is able to offer line *and* service for the same price rather than just an add-on to a required AT&T line.
To those who say less competition means better service, maybe. I doubt it, maybe in sports it's a level of performance competition, but business? I don't doubt that competition means better price competition and more choices competing for my selection, and will be hard pressed to believe otherwise.
