I'm sorry
When comparing mobile phones, you have to bear in mind the operating system.
I use Windows Phone right now. The number of times my smartphone has crashed, in a variety of situations, often seemingly completely arbitrary, is depressing - especially since I went out and bought no less than 3 of the bastards for myself and members of my family, this year, in a bid to seek something new and potentially better. There are issues with getting real-time data, including battery data, push e-mail, recognising networks, and obvious bits of functionality left out. This is still a half-baked platform, not a serious option for someone who needs a functional and reliable mobile device. I used Android before, and iPhone before that, and although each had issues, they were less frustrating than this.
