[DISCUSSION]Satisfied with updates ? xperia s,sl,ion,acro s topic

i am a xperia s user who got this phone during ealry 2013,maybe i am late but xperia s isnt that old as many people think.launched with android 2.3,updated to android 4.0.and took a year for a final android 4.1 update.updates were good but i feel xperia s was killed before its life cycle,because of sony delays.and what about xperia ion,its still left with .200 buggy firmware.if 18 months is the life cycle,is the matter all say to justify,what about xperia sl.it is still in its living stage.i just wanted to know am i the only to think so or there are more people who think the same ? and dont give the reason about snapdragon s3 drivers.if sony really wants to update,its not hard for a big company.please share your thoughts.xperia s and its brothers deserved a taste of kitkat but killed coz of the update delays :)
