Apple is still gaining customers in phones, and still gaining them in PCs. Your assertion is patently false. In fact, the iPad has made Apple the largest PC manufacturer in the world by units, nevermind profit:

80% of this quarter's drop in iPad sales is due to reduced channel inventory. In other words, sellthrough is nearly the same as the iPad 3's launch quarter, but Apple isn't restocking the shelves in preparation for the next fleet of iPads.

In unit sales, yes. In profit? Not really.

Anyone know why they separate Kindle Fire and Android? The Kindle Fire runs Android, although a heavily modified version, but it's still an Android.

As usual, the VGChartz demographic will tend to skew towards more spec-chasing personalities, which is not the wider market Apple serves, so your anecdote does not necessarily reflect reality any more than my anecdotal evidence that 9 in 10 tablets I see at the mall or on the bus are iPads.  So you're right that more data is better.  I couldn't find a recent tablet-specific study (though here's one from early 2012 that gives iPad 95% share of e-commerce transactions on tablets).  So instead here's the June 2013 web usage across all mobile devices:

This is globally, not just North America.  The iPad accounts for 34% of all smartphone and tablet web usage, and all Android phones and tablets combined come out to 26% (see different chart on the same site).  Now obviously Android phones far outnumber Android tablets, so I hope you'll agree that a large chunk of that 26% is just phones.  If so then simple math dictates that the iPad has a very commanding share of tablet usage, and even in the absurd sccenario that no Android phone user ever opens the browser, that still gives iPad 56% of all tablet traffic.

EDIT: I wish there was more direct data available, but none of the big players besides Apple is willing to say (on a regular basis) how many tablets they sell: not Amazon, not Samsung, not Google.  Even when they do it is usually "shipped" and not "sold".  A cynic might be led to conclude that the reality is worse than third-party estimates, so they prefer to let others make assumptions.

There are important differences depending on who you are. For example, developers need to deal with a different app store if they want to target Kindle users, with different requirements, services, and terms and conditions. If you're Google, your default search status is gone and all your apps and services have been stripped out.

Even the end user, who might supposedly use the same apps and services whether it's a Kindle or a Nexus, will find that the default apps and services guide their usage patterns. Most people tend to go with the default, unless they have a very compelling reason to change.

It's been estimated that a third of Android devices have no Google services at all, leading analysts to joke that Android is not a platform itself, but rather a platform for platforms.

Said someone with no understanding of the needs of the average tablet consumer.  Sure, 16:9 is nice for watching movies, but tablets are more than just glorified digital photo frames.  For the many tasks better suited to portrait orientation, 4:3 is preferable.  It's also slightly more "honest" in that it provides more screen real estate for the same diagonal length: the iPad mini's 7.9-inch 4:3 screen has a area of 30 square inches, the equivalent of an 8.4-inch 16:9 display.

Tim Cook said it best. ~85% of all web traffic for tablets are run through Ipads. If the Ipad is losing share to all these tablet makers, what are people doing with these tablets? The Y/Y drop is more attributed to Apple not having a April-June release of an Ipad like it has the past two years prior.

Mobile devices are reaching a saturation point. A $300 - $400 device suits almost any need: more than enough power for all main purposes, HD screens etc. In a years time these devices will move to a $200-$300 price range and lower after that. It's the same thing that happened to PC's years ago. Expect for games or pro work there is no need to upgrade or go more expensive.

Well said, and the rapid growth of the Chinese market will only further enlarge this "dark ecosystem" of Android devices which contribute nothing to Google.  Benedict Evans estimates that it is already quite close to outnumbering all iPhones.

Finally people are realizing those things are useless. Hopefully PC sales go up now.
