i dont mind this at all.
i mean i don't get caught up in the version numbers per se, but the features.
i honestly am not really sure what is so different about 4.2 and even 4.1 other than it hink some stuff in the settings bar is slightly different. 4.3 added trim support natively but from the anandtech review i know moto backported that to their version of 4.2.2. so that doesnt matter either.
4.4 at least i figure is a big enough jump. before the moto x i was using a razr M on 4.1.2 and honestly i can barely tell the difference OS wise between any of these (and i had 4.3 on a nexus 7 for a while, honestly all the jelly bean labeled 4.1-4.3 variants are basically the same)
