Apple G4 iBook series

The iBook G4 is a rugged notebook, well suited for students and home users who want a small, affordable Mac notebook.

Open the lid, and you begin to notice obvious improvements over the previous model. The keyboard feels more solid due to a redesigned internal cast-magnesium metal frame underneath. The keys don't pop off as easily as they did on earlier models, and the keyboard colour now matches the matte white of the palm rest and the display frame.

The iBook G4 adopts some of the PowerBooks' design details. For instance, the latch that holds the lid closed retracts when the lid is open, and the battery includes a built-in power-level indicator. We like the new slot-loading optical drive, which eliminates an easily damaged CD tray, and the 12.1-inch, 1,024x768 display produces crisp images and bright colours. The screen is a little small for watching movies, but with the addition of a AU$35 TV adapter cable connected to the VGA port, the iBook works as a DVD player for your TV.

Apple has corrected a problem that caused some iBooks to fail after a few months of operation. The unit we had showed no sign of a defect on the logic board. Apple's iBook Logic Board Repair Extension Program is paying for motherboard replacements, even for units with expired warrantees, and is refunding owners who had previously paid to repair the problem.

The Apple iBook G4 is the last Mac to abandon the G3 processor in favour of the faster G4. The upgrade also includes a new 133MHz system bus. As Apple's entry-level notebook, the 12-inch iBook G4 has an 800MHz processor; the 14-inch ups the ante to 1GHz. One of the biggest improvements over the previous iBook is the significantly faster video hardware: an ATI Mobility Radeon 9200 graphics card with 32MB of video RAM. We found that this made for smooth 3D games, such as Quake III and the bundled Tony Hawks Pro Skater and Deimos Rising. Also included in the base price are a 30GB hard drive and 256MB of RAM. Unfortunately, the 640MB maximum still holds for the iBook. This won't be enough for professional multimedia authoring or for serious use of Microsoft's Virtual PC.

Apple made good choices for connectivity. There is no PC Card expansion slot, but you can add peripherals via two USB 2.0 ports and a 400Mbps FireWire port. A VGA port lets you connect an external monitor. Networking is covered with a built-in modem, a 10/100Mbps Ethernet port, and an AirPort Extreme (802.11g) wireless network slot located under the keyboard. The card is a reasonable AU$199 option or you can install your own. Built-in wireless Bluetooth is available for an extra AU$99. We used a USB Bluetooth module from D-Link with the iBook, which worked with Apple's Wireless Mouse and Wireless Keyboard without requiring any additional software.

Other preinstalled software includes AppleWorks, a demo version of Microsoft Office, Quicken, World Book 2003, and Apple's iLife '04 multimedia suite.

Thanks to its across-the-board improvements over the iBook G3--from RAM speed to CPU speed to graphics adapter speed, not to mention a more capable version of the OS--the 800MHz iBook G4 easily outpaced the older 12-inch iBook, the 900MHz G3, in all of our performance tests. Although the iBook couldn't match the PowerBook 12-inch 1.25GHz G4 in performance, its strong showing makes it an affordable alternative to the pricier PowerBook.

CNET Labs uses three different applications (iMovie 2.0, iTunes, and Quake III) to test Apple's notebook performance. With iMovie, we convert a large movie file into QuickTime; with iTunes, we convert a music file into an MP3 file, timing each procedure. With Quake III, we run the standard Timedemo 1 at a resolution of 1,024x768 with default settings.

In iTunes, the iBook 800MHz G4 delivers a 49 percent increase in speed over the iBook 900MHz G3 when encoding a large MP3. Our iMovie test on the G4-800MHz indicates a speed boost of 48 percent over the G3-900MHz. Compared to the PowerBook G4-1.25GHz, the iBook G4-800MHz is a close second in iTunes, iMovie, and Quake III.

Thanks to its 50WHr battery, the iBook G4-800MHz lasted nearly 3.5 hours. This compares favourably to the PowerBook G4-1.25MHz with its 47WHr cell, which lasted only 2.4 hours, and the iBook G3-900MHz, which has a 46WHr battery that lasted 3.1 hours. The PowerBook is somewhat handicapped in this test because of its faster 1.25GHz processor, which draws more power and, as a result, gives the system less battery life. In order to drain the battery of an Apple notebook CNET Labs plays a DVD movie in full-screen mode with the sound on.

Apple's warranty is a fairly standard one year for parts and labour, though the toll-free telephone support lasts for a fleeting 90 days. You can extend both the warranty and the phone support to three years for an extra AU$449. Apple does provide self-help resources, such as an Apple Hardware Test CD, included with the iBook, to help diagnose hardware problems, and Apple hosts an extensive knowledge base and a large discussion board on its Web site. The 100-page paper manual includes various troubleshooting topics and provides good illustrated information on adding memory, replacing the battery, and connecting to the Internet.
