You would think that Google could afford to hire some people to do bug triage. Users reporting bugs are trying to help Google (and themselves, admittedly). Presenting users with a "write-only" bug database is worse than no bug database.
Galaxy Nexus with EMMC chip V3U00M of 08/2012 or 09/2012 (+others) needs fstrim'ing (or mounting with discard option). Android does not do fstrim in Galaxy Nexus, therefore phone becomes unusable after simply using most of the storage, and the user has to root their phone to fix it.
