All that says is that the market has grown... so Apple's share is 15% down but their actual (extremely profitable) unit sales were up 26%... market share loss/gain is only of major significance when the market is static... and it isn't yet!
Any company would be happy to increase their profitable sales by 26% and Samsung are not as financially wonderful as implied, take a look at their financials if you're really interested (they're online) and bear in mind that electronics is also only a small part of the company...
I'm not prejudiced in any particular direction unlike some on these boards... I have a Samsung Galaxy IIS smartphone, an iPad 4, an Android tablet, an iMac and a Fujitsu-Siemans laptop amongst other things... I like and use them all but the Android tablet and laptop are starting to lose ground now I have the iPad because it does so much of what I want without problems or wasted time...
