Last week, Apple unveiled the latest generation of MacBook Pros, which now feature Intel Haswell processors, PCI-e connected flash storage and nine hours of battery life.

Despite their popularity, Apple Mac computers still take up only a small chunk of the PC market. But reviews are coming in, and the newest iteration of the iMac, with its thin display, power processor and innovative hard drive, may convince a lot of users to switch to Mac.

The principle difference between the way that Google deploys its Android mobile operating system versus Apple's approach with iOS is that Google licenses Android for use on many different devices.

Given how popular the iPad 4 is, it seems natural that the tablet industry would be doing really well as a whole, as users may want the advantages of a touch screen interface and intuitive apps but may prefer models produced by other manufacturers.
