And back to topic, GS4. Why?
1. Both the inspire and One X had terrible battery life compared to captivate and galaxy S3 in my experience.
2. It has always been as easy as follow 1,2,3, so on simple instructions to take off the touchwiz from a galaxy, and install AOSP. Love that. ODIN is brilliant. I could be a noob for example, but flashing a firmware through odin would be no different from flashing evasi0n on iPhone. Dirt simple. No S-On/Off crap, no need to go to a site unlock bootloader. No need for anything.
My biggest reason to buy GS4 is just that: easy AOKP ROM on it while enjoying the camera, battery, audio, and a 32GB expandable storage.
My turn off would be SAMOLED. If it is bright enough however, i won't have an issue.
I have no love for sense however. I would rather use vanilla android. That is just my opinion.
