Coming from WebOS I thought I wouldnt be satisfied with any other OS, especially after experiencing how awful the Iphone is compared to WebOS. But Palm was no more and I needed somewhere to go. So this is my fist and only Android (Nexus S 4g) so far. I have not been disappointed with it at all like I thought I would be. Almost two years when I got this phone and it still is running like a champ. Google has some of the best services out there.
