Audio is important to me so I sure hope my next phone has a way to use add-on amps and DACs from the likes of iBasso or Fiio. Of course it would be best if the phone came with very good DAC and amp, but that is asking a lot. The price would be too high for those to whom audio is not that important. The iPhone has this ability through the use of a LOD, but I do not want an iPhone for reasons previously mentioned in this thread. The camera in the EVO4G is good enough for me that I feel no need to pack a digital camera around. But, I still feel the need to pack my Sansa Clip+. I do now find myself listening to streamed music more and more. Things such as MOG which stream 320 kbps. The audio from the EVO is ok, but I wish it was better. A comparison to the HiFiMan HM-101 ($40) on a laptop shows how deficient the EVO is in good sound.
So I am waiting for my next Android to have ICS w/usb Hosting, LTE, and a kickstand. My contract is up in November. I'll likely wait until then.
