IMO too many pitfalls with sideloading. lots of variables and lots of things that can go wrong if you don't follow the instructions exactly. i've read a few horror stories already. and my ADD/OCD is not conducive to following precise minutial instructions that vary from source to source and vary upon equipment and method used - OTA Zip, Factory Image, Toolkit, Unlock, Root, Windows 7, 8, 8.1, Mac, etc. too much risk. poor risk/reward ratio. i don't need to brick my only phone - which is my primary mode of communication - especially on a Sunday night when everything is closed. it sucks but i've waited this long i might as wait a little longer for the official OTA.
