It really bugs me when people can't separate the device from the OS and bitch about all these issues it has when the culprit is just that 7.0.4 needs to bump to 7.1 pronto.
Seeing as how he cannot upgrade to 7.1 currently unless he is a developer, or does it illegally, it's not his fault that he can't separate the two.
Even if he could, he is still completely right to complain about a malfunctioning device--whether the root be software, firmware, or hardware. For the general populace, they are buying a device in the singular.
For a premium tablet, it should not have these basic problems (safari crashing, yellow screens, restarts, resprings, etc.)
I have owned almost every Apple product (iphone, ipad, macbook, etc.) and this is the worst one I've owned. My 4 year old 17 macbook pro has fewer problems than my brand new ipad air.
