+ 0 Votes Android (Closely Followed by iPhone) brett.sheeran 4 years ago I have spent a lot of time using both the Android and iPhone operating systems. Frankly, the iPhone UI is just a bit more polished. However, I prefer Android because the OS isn't as restricted as the iPhone. If you are considering an Android device I suggest only considering the 1 GHz models such as HTC Incredible, Nexus One, Motorola Droid. If you are considering an iPhone, I suggest holding out for the next generation due mid-year. The Palm Pre and late model Blackberries have much to recommend. However, while those devices might be popular now, I think their market share is reducing.
