Other than the backlight glue issue, which seems to be related to yellow tint, edge imperfections, etc, most could easily be caused by user-specific Internet providers, etc.
So many of the issues have been myths that it seems unproductive to call them inherent flaws. Things like:
"the smart cover is depositing screen damaging stripes on the display."
"The magnets will wipe out the iPad's hard drive" (my favorite

)
"video playback is much worse than iPad 1!"
"the iPad will overheat with a back cover installed."
"the iPad 2's glass is thinner so it will break more easily."
Etc.
Separating fact from myth is important for new forum members trying to find accurate information on widespread flaws.
