As usual after a launch weekend, Apple has something to brag about — 3 million iPads sold in 3 days. To put that in perspective, that’s double the sales posted in the opening weekend of the iPad 3 back in March.

That’s definitely good news for Apple, but what does it really mean for the iPad Mini? According to Apple’s press release, that 3 million includes all of the iPad models currently in the lineup. That includes the iPad Mini, iPad 2 and the iPad 4 with Retina display.

The fact that Apple didn’t single out the sales numbers from the iPad Mini may be significant. Instead, the press release quoted CEO Tim Cook, saying that Apple “practically sold out of iPad minis.” That means that Apple’s analysts are really good at their jobs, but it doesn’t mean iPad Minis were an unmitigated success.

I’ve certainly read mixed reviews about the Mini. The underwhelming screen resolution has definitely been a common gripe from reviewers like Daring Fireball’s John Gruber. Amazon sure didn’t pull any punches on its homepage…

Clearly, it’s the Mini that most of us in marketing world are concerned with — because it’s designed to compete with other mid-sized tablets like the Kindle Fire HD and the Nexus 7. The battle for tablet supremacy is HUGE because it will determine which OS users will ride in on when they navigate to your site.

Currently, if your site is optimized for Android and iOS, you’re basically all set. Microsoft is definitely looking resurgent, and most my tech addict friends are excited about the Surface.

Do you think the Mini is a game-changer? Or is one of Apple rare “me-too” products?
