Really, everything about this phone is absoulutley awesome.
These are the things that are starting to annoy me however:
Once you use a phone with a bigger screen for awhile, its really hard going back, retina display or not. Lastly, this phone should've, could've been released with LTE, but 3G in my area (Verizon) is decent, but LTE speeds would be great on the next iteration. If I do push this phone through the day, I'll be scrape a day of usuage, still better than the 2 hours of moderate us from my Palm Pre. But as a phone, its flawless, as any device, its one of the best in the industry. But trends with bigger screens and better network connectivity are making the iPhone a harder choice for new buyers.
