The G3 processor from the iBook is one generation behind Mac desktops, whereas the ThinkPad's Celeron is two generations behind other IBM-compatible notebooks. Even though Celeron is somewhat obsolete, it runs at 466 MHz versus G3's 300 MHz. Since neither processor is top-of-the-line, and both notebooks are in the same price range, it is safe to conclude that the two notebooks are comparable. Apple declares that "fast, easy access to the Internet" is among the "features [that] made the world fall in love with the iMac" (Apple). As mentioned earlier, the Internet performance is one of the uses for home computers and should be thoroughly tested. In their review, PC Magazine uses i_Bench to test the Internet performance. According to i_Bench tests, ThinkPad outperforms the iBook on almost every test (Hill 53). The only exception is the test of QuickTime Transition Effects - the iBook is faster than the ThinkPad (Hill 53). Apple's QuickTime is one of many formats for viewing compressed video on the Internet and is rarely used because of poor compression quality. QuickTime should not be used to test the computer's performance for several reasons: it is rarely used, and is most likely optimized for Macs. On the other hand, The Java Virtual Machine test should be looked at more carefully. Java is a platform-independent programming language originally designed by Sun Corporation for another operating system, and is currently used for writing programs for the Internet. This test runs several Java programs within a browser, which simulates ordinary Internet browsing better than QuickTime. The ThinkPad impressively outperformed the iBook with the a score of 43,766 versus just 23,872 (Hill 53). Comparing the iMacs with IBM-compatible desktops creates the same problem - finding the PC that is comparable to the iMac. Dave Glue, a programming student, sums up this problem in one sentence: "If you're going to downgrade the PC to exactly match the iMac's MHz rating and hard disk, you'll have a significantly cheaper PC than the iMac.
