Of iMacs and Apps

Apple introduced new iMacs with larger screens. Resellers reportedly expect demand for these computers to be strong.

"With compelling new products like the new Macs, I think Apple will continue its share gain in the PC market even though it's not currently playing in the fastest-growing segment, which is netbooks," Broadpoint AmTech's Marshall said. With Cupertino having about 5 percent of the global PC market, Marshall thinks it has plenty of room to grow.

Meanwhile, the iTune Apps Store, which is already the clear leader of its market, is running away from the competition. There are about 101,500 apps in the store, almost 93,000 of these are active, and there are more than 22,000 unique app publishers, all according to the tracking Web site 148apps.biz.

That puts the iPhone in a secure position, as a wide availability of apps enhance the mobile phone experience for many consumers. They are such an important factor in handset sales that wireless phone carriers, handset manufacturers and even Google and Microsoft are setting up their own app stores.
