You can't use Best Buy to find specs. Just go to the manufacturer's website or to a trusted third party site.
Sites that only sell stuff usually have specs intended for the non-technical community. For example "with 1.6 GHz CPU". That tells you nothing.
This applies to things like cameras, microphones, headphones, computers (including smartphones and tablets) and God knows what else, because most people don't care about those kinds of details.
Although something as basic as supported SD card size should be something worth mentioning.
Where did you get that information Strollin? I can't find any specifics here
