Shoot, even Windows Phone doesn't even need a dual core processor. Comparing a Lumia 900 with Windows Phone 7 and the 920 with Windows Phone 8, there hasn't been a significant improvement with the overall user experience, they're both smooth and slick regardless of processing power.
I just want superior HD crystal clear call quality, very long all day and then some battery life, and video calling that makes me feel I'm with the physical person!! It's a phone, not a PC!
If my phone was 10 times slower and lasted twice as long on a charge, I would be very happy about it. My phone is almost instant in every single thing I do and I don't need that.
Some of you obviously don't understand smart phones. When I go on a trip, I can bring up Google Maps and pinpoint my position in an instant. I can see where all the petrol stations are, all the restaurants and all the hotels. When I find the hotel the number is there I touch it and I'm ringing the hotel. I can use it as a navigator with the car app on the HTC absolutely brilliant. The Navigator finds the satellites in an instant, much faster than my $400 Navman, and it looks better and is more accurate.
If I get bored I can watch Adele singing in HiRes or watch a video on YouTube, get the latest weather reports in an instant from BOM. I suppose I could go on all day, but theses powerful smartphones are truly unbelievable.
Going from a Windows Phone with a single core CPU to a one with a dual core CPU, I've only noticed somewhat faster load times for recoded Windows Phone 8 apps, as well as being able to view 720p video. It's a nice improvement for sure, but ain't nobody going to be using a quad core for that!
I've had both the HTC Desire and One X, believe me you need those quad cores on a big bright screen, unfortunately battery life does suffer. Although with very heavy use I can easily get a full day and a half, with moderate use 3 days and light use 4 days since the Jellybean upgrade.
I have been working with an iPad mini at work and I don't consider the display crappy.
I'll stay with Razor (2006), and my horse Bill to get me home (he doesn't use GPS).
