ics is fine. its the actual phones that may have issues. thats a hit and miss. i know several people who had the maxx before ics came out and once they upgraded they fell in love w their phones all over again.
its just like the issues people get with gnex. some people have horror stories as others have nothing but positive praises.
why a maxx though? u can get the s3 and have just as much juice.
unless u wanna wait for a completely brand new unannounced phone in a month or 2.
