12-inch powerbook G4 information
The arrival of the 12-inch PowerBook G4(high quality apple powerbook G4 battery) at the beginning of this year was big news. The Apple faithful finally got an ultraportable; in fact, the 12-inch PowerBook was (and still is) the smallest notebook ever to come out of Cupertino. But to pare it down to size, Apple cut a few corners from the original. This update retains everything we like about the design, but it addresses many feature shortcomings by adding a faster processor and graphics, room for more memory, and analog and DVI outputs. Bargain hunters will find that the just-announced 800MHz iBook offers similar portability and features (not to mention longer battery life) for $500 to $700 less, but pound for pound, no other Mac offers as much as the 12-inch PowerBook.
The 12-inch PowerBook is the smallest and lightest notebook available from Apple, albeit by a slim margin. It measures 1.2 by 10.9 by 8.6 inches and weighs 4.6 pounds. The more affordable 12-inch iBook is a few tenths of an inch bigger in all dimensions and weighs just less than 5 pounds.
Like most Apple notebooks, the 12-inch PowerBook resists categorization. It is notably heavier than most Windows-based ultraportables, such as the Dell Latitude X300, the HP Compaq nc4000, and the IBM ThinkPad X31, which also carry 12.1-inch displays. The comparison is misleading, however, because the 12-inch PowerBook has an internal media drive, putting it in a similar league as thin-and-lights, which despite the name, are slightly bigger and heavier than ultraportables.And apple powerbook G4 laptop battery is hi-capacity and cheap,maybe a battery replacement is also so good.No matter how you look at it, the 12-inch PowerBook strikes an excellent balance between portability and features.
The anodized-aluminum case feels very solid and seems to resist scratches better than the old titanium cladding. Some users have reported that the metal case gets toasty, but we didn't find it to be unusually hot. The 12.1-inch display, with a 1,024x768 resolution, opens and closes on a sturdy hinge. You can adjust the display brightness from the keyboard or in System Properties.
Apple has added a mini-DVI output port.
The updated 12-inch PowerBook now comes in two standard, and virtually identical, configurations. Both include a 1GHz PowerPC G4 chip, 256MB of memory, and a 40GB hard drive, expandable to 60GB or 80GB. The key difference is the optical drive: the model with the combo CD-RW/DVD-ROM starts at $1,599, and the one we tested with the SuperDrive (CD-RW and DVD-R/RW) costs $200 more. Beyond that, there are few configuration options.
Nevertheless, most users won't find the 12-inch PowerBook lacking,and they like stronger
apple powerbook G4 battery ,especially since Apple has addressed the few weaknesses in the initial version. You can now increase the memory to 512MB, 768MB, or 1.25GB. And both models use a faster graphics processor: the Nvidia GeForce FX Go 5200 with 32MB of DDR SDRAM. There's still no L3 cache, but Apple insists that typical users will never miss it, and we're inclined to agree.
Though the original 12-inch PowerBook had a mini-VGA connector for connecting to analog monitors, projectors, and composite-video devices, such as TVs and VCRs (via an included adapter), it lacked DVI or ADC outputs for digital flat panels such as the Apple Studio and the Apple Cinema displays. Apple has corrected this by adding a mini-DVI output. The corresponding mini-DVI adapters for analog (VGA) and digital (DVI) displays are in the box; a mini-DVI-to-video adapter for S-Video and RCA (composite) video gear is an extra $19. The remaining connectors include audio in and out (headphone), two USB 2.0 ports and one FireWire 400 port, and 100Mbps Ethernet and modem jacks.
While these changes are significant, the 12-inch PowerBook is still missing a few features found in the larger and costlier 15- and 17-inch models, including FireWire 800, standard AirPort Extreme networking, a PC Card slot, and standard-size video outputs (VGA, DVI, S-Video, and RCA). An AirPort Extreme card will cost you another $99, but at least the 12-inch model includes Bluetooth.
Finally, the model we tested ran Mac OS X 10.2.7. Panther (Mac OS X 10.3) is also available for $20 until December 24, 2003. (Apple sends you the Panther discs; the installation is easy.) After that, the notebook will ship with Panther. The 12-inch PowerBook also has the usual assortment of Apple software, including the iLife bundle and third-party trialware.
On most CNET Labs test, the 12-inch PowerBook delivered the performance boost we expected to see: it was on a par with or slightly faster than the previous 867MHz model on our iTunes and iMovie 2.0 tests. (In iMovie, we convert a large movie file into QuickTime, and in iTunes, we convert a music file into MP3, timing each procedure.)
Apple powerbook G4 15-inch review
In the other side,15-inch powerbook G4 is also very well.
Three years after the popular Titanium PowerBook and
apple powerbook g4 titanium battery
debuted, Apple's new 15-inch PowerBook G4 improves on the original in nearly all areas except battery life. The notebook has the same sleek design as the titanium model but with an anodized-aluminum case and faster hardware. The $2,600 version includes a backlit keyboard that turns on when a room gets dark, a feature previously available on only the 17-inch PowerBook. In fact, this new model offers such an excellent combination of features and price that we wouldn't hesitate to recommend it were it not for reports from some early customers of display problems, specifically faint white spots on the screen. We didn't encounter this issue on our test system, and Apple says that it is investigating, but once it is sorted out, the 15-inch PowerBook will secure a position high atop our list of recommended desktop replacements. Like the Titanium PowerBook before it, the 15-inch PowerBook hits a sweet spot in size. It's big enough for a wide-screen display (1,280x854) yet small enough to carry with you. The 15.2-inch screen fits snugly in the PowerBook's 13.5-inch width and 9.5-inch depth, but the unit measures a mere 1.1 inches thick. Both sides of the lid contain internal antennae for AirPort Extreme, otherwise known as 54Mbps IEEE 802.11g wireless networking.
And apple 15inch,17inch powerbook G4 computer,apple powerbook G4 battery and battery charger have past test.So they are better than the others.
