I do.
I'm giving away my 5800 XM and getting an iPhone.
why? 'cause the tons of apps and the display.
The apps are over-rated and you can get them on any other device anyway. As for the "revolutionary" retina display, it's all just false marketing. More pixels than the human eye can differentiate is nonsense. What would be the point? Just to pretend you're better than the conpetition? That's right. A more accurate retina display would be closer to 477 pixels per square inch at 12 inches instead of the 326 Steve Jobs claims. More bs marketing from Apple, what else is new? It's too bad. iPhones have the best interface and straight up use-ability of any phone on the market. Why they hide behind false marketing and hold back on the tech is beyond me. The iPhone 4 was already behind the industry standard when it was released.
Anyway, As far as I can tell, the Super AMOLED screens are superiour in viewing angle and sunlight viewing, after that it's all equal.
I have an iPhone 3GS, but until Apple adopts Flash, better cameras, transferable storage, real blue tooth tech, and total customization, I'll never own another iPhone again.
