Actually, the stats show that the decline is across the board in the Tablet market with the Android segment much farther down than the iPad segment. Samsung has hit a 30-40% decline. So far this Christmas season, sales of iPad seem to be roaring.
Part of this decline in Tablets is the effect of large inventories of unsold white box Android junk in inventory which was shipped in previous quarters being now being deeply discounted which is now competing against orders for new white box Android junk tablets from being shipped which means they remain in manufacturers' warehouses. Can we say they are overstocked? We may start seeing some of these in cereal boxes as free give-aways. . . just to get rid of them! LOL!
On the other hand, when these Junk Android tablets were being heavily discounted for Black Friday and Cyber Monday, several Computer Security companies analyzed them and found that almost ALL of them were shipping pre-rooted and many already had malware already installed capable of stealing IDs, remote exploits, and some even had key-loggers installed! Some of these were being sold with what consumers would assume were "trusted" names such as "Pioneer" and "Bell and Howell," etc, but they were still basically no-name white box Android tablets, often running antique Android as old as 2.1 with no way to update.
Apple is selling what they have manufacturedtheir just in-time systems try to maintain a three to four week supplybut the sheer numbers of cheap under $50 crap out there makes it look as if they have lost market share to Androidtablets that really have little capability that are really not anywhere near the same league as an iPad or a Samsung Galaxy Tab, mere Toys.
