Don't drop the whole series based on a few bad experiences. I have been using a Galaxy Nexus since they came out, and a Nexus 7 for almost a year (both currently at 4.2.2 via normal OTA updates). Neither has had any of the problems described. Lemons happen. Also, these are complex machines that run complex software; malware happens too, as does innocently-perpetrated excessive resource consumption by background processes created by third-party developers that either aren't careful enough or simply missed something complex. There's a lot of reasons things like this can happen. By many accounts the Nexus 4 does actually have serious issues in a lot of ways... of course, there are also many people that have and love this phone, too. Don't judge the entire line based on a few complaints.
