For me, I found android out of frustration with Blackberry, and Tmobile's lack of commitment to releasing serious BB hardware. At&t released the Bold, Verizon released the Storm, and Tmo's big BB release? A stupid flip BB!!!

Tired of my Curve, at the end of my rope about to leave for Verizon, I read google was putting out a new OS that would rival the Iphone OS. And the device would be released on Tmo to my surprise. I continued to follow the development closely and preordered the G1 the 1st hour it was available. It blew the doors off my Curve in every way and I fell in love with the young OS.
Yes Android has come so far. I remember when you could scroll down and hit the bottom of the android market!lol Even though Android continued to grow rapidly, Tmo still seemed to be clueless about releasing serious hardware. After the G1, I got the My touch 3g, and the Behold 2, but couldn't stand watching Sprint get the Hero and Verizon get the mighty Moto Droid. It was clear tmo is a kiddie company not ready to compete with the big boys for my money. So I left and got my Droid. It's been the best move I could've made. I don't care if it cost a little more for Verizon's plans. This company is dead serious about Android and that's what matters to me. Sprint is also serious.
To think after all this time tmo just released the 1st TRUE upgrade from the G1 with the Vibrant. Its madness! Meanwhile, the Droid became the most successful Android device ever, and now i'm enjoying Android at the highest level on my Droid X. Life is good!
