Although everyone I know seems to have Verizon, I have been a Sprint customer for more than 4 years. I currently have the HTC Hero, an android phone (similar to the Droid). I love it...for me, while I do make calls, my phone is my primary internet tool...Facebook, Twitter, and looking up phone numbers or random things. I love it. And while I am a Mac person, right now I am not willing to pay twice as much per month for AT&T just to get an iPhone. I am seriously considering switching to Verizon when my contract runs up, though, so I can finally get an iPhone.
As a whole, I love android and all the apps...I have yet to pay for an app, since i have all I need for functionality. The rest are for amusement, pretty much (like an app that just plays the sound of crickets...I use it during amusingly awkward moments...goes over very well

).
Oh, and while I would say I get approximately one dropped call a month, I am pleased overall with Sprint. I get unlimited internet, SMS, MMS, and 450 anytime minutes (plus I can call ANY cell phone on ANY provider for free), plus equipment protection, for $67 a month with all the fees. I have a discount from a former employer, which understandably lowers the bill substantially (by about $15 a month), but it's just so darn cheap. I use the phone to make calls moderately, but have never come close to using my minutes, primarily because most of the people I call are using cell phones, so it doesn't touch my minutes.
