I upgraded my phone and iPad to iOS8 and aside from it taking a really long time (for the iPad it was an overnight job), I noticed that the Apple ID (or is that aPPle iD–seriously who cares about your stupid abbreviations Apple) was attached to an email address I no longer have. Considering I changed my Apple account ages ago, it was puzzling to see the wrong address on the screen.
As pretty as Apple products are and as solid as their hardware, some things are just dumb. So, hey Apple, knife.
