The Display and Fiber Optic Keyboard Lighting

The display on the PowerBook is one of its strong points. While it doesn't hold a candle to Apple's desktop Cinema Displays, it is quite strong as a notebook display. I'd say that the display on the PowerBook G4 is one of the best, if not the best, display which I've ever used on a notebook. The 15" display has a native resolution of 1280 x 854, which is what you can expect from just about any current generation 15.2" widescreen display.

Apple outfitted the Powerbook with ambient light sensors to control two things: the brightness of the display, and the fiber optic backlighting of the keyboard. The light sensors for the screen are located behind the grilles for the speakers, on the left and right of the keyboard.

Both features can be overridden, but their pros generally outweigh their cons. The best example of their use occurred while I was writing this very sentence on a flight over to Taiwan. Given the length of the flight, there are many times when the lights in the cabin are dimmed as well as brought back up again. I started writing while the cabin lights were dimmed, which caused the Powerbook's sensors to activate the keyboard lighting and dim the screen. About two hours before I landed, the cabin lights were turned up for breakfast service. Almost instantaneously when the lights went up, the brightness on the screen increased (to compensate for the higher ambient light) and the illumination on the keyboard turned off. The same types of features are useful for office environments when the lights are turned on after the end of a presentation, or in a school environment when the same occurs.

The fiber optic lighting on the keyboard is fairly impressive. Instead of being lit by a few LEDs causing bright spots on the keyboard, the face of each individual key is lit using a fiber optic network of lights. Only the letter or number on the key is illuminated; for example, the majority of the F key remains unlit, but the letter "F" itself is lit creating a very unique effect that is very well appreciated by someone who has to type in the dark a lot on airplanes.


We apologize for the blurriness of the image, but you get the point.


The fiber optic lighting isn't without its weaknesses; for starters, it does help contribute to the cost of the PowerBook, but that's not a huge issue.

You can control the degree of lighting by using the F8 - F10 keys on the keyboard. F8 will turn the keyboard lighting off, F9 will decrease the level of illumination and F10 will increase the level. Depending on how you have your keyboard settings configured, you may or may not have to hold down the "fn" key.

    I just read this and several other Mac articles here last night. Funny thing is, several weeks ago when my "enterprise" HP laptop started flaking out on a business trip, I was at the point where I was considering buying a Mac Mini just to play with. This was after reading about the current state of Tiger and the platform in general.

    Instead, I ended up walking out of the store with a new 17" Powerbook, which is no heavier than my 15" HP, and infinitely more pleasurable to use, in so many ways. After loading Office for the Mac, iWorks, Deltagraph, Acrobat and Acrobat reader, and bringing my files over, I was ready for a subsequent three weeks of business travel, and haven't looked back since.

    I'll need the HP to run some of my CAD software (schematics and PCB design), but I'm pretty sure now there will be a G5 dual processor system in my future running those apps under Virtual PC.

    Perhaps some of the adoption process and uptake wouldn't have been as smooth with earlier versions of OSX, but some days I just wonder why I didn't do this sooner.

    BTW, I've been using PCs since 1983, and building them since 1985, so it's not like I'm not quite immersed in that scene, especially due to the CAD work (electrical and mechanical) which I do. For now, I'm learning Ashlar Vellum Graphite, and thinking I should have done that long ago, too. (Adios, AutoCAD).

    BTW, the 23" Ciinema display is great- not that my Samsung 213T is obsolete, but the integration factor for the Apple is a big plus. And this silly laptop DOES have dual DVI and can drive the 30" display, too. Hmmmm. ;^)

    "For example, if you have a file, drag it into an open Terminal window and the entire path to that file will be copied into the window for you. It actually makes interacting with the file system from the command prompt quite easy. "

    Windows command prompt allows this too

    I bought a PowerBook 15" 1.5ghz about 4 months ago (my first Mac for all intents and purposes).

    As mostly a PC user (Windows + Linux), I agree with a lot of what Anand talks about in the article. I think most people coming from a Windows background could safely make a purchasing decision based on that article...

    For the record, what really sold me on the Mac (particularly the PowerBook) was running into it EVERYWHERE at my last Java symposium: "No Fluff Just Stuff". As a Java developer, it just seemed liked the perfect package: a) no Windows in sight, b) UNIX on a notebook without having to install it myself, c) the best OS GUI on the market IMO.

    The reservations about the 1 button mouse on the G4 are definitely understandable. But somehow (for whatever reason) it really doesn't bother me. However, when I'm at a client site and developing for long periods of time on the G4, I do carry a Bluetooth mouse with me. It's one button also :)

    wonderful job with all the articles related to this. i can't believe i read the whole thing. =D

    there's one thing that i haven't noticed though. you never mentioned the sleep freature in the Powerbook, where you never really have to turn off your laptop. so whenever you need to use it you just take it out open it and it's ready to go.

    unlike PCs, you have to turn it off, standbye, or hibernate. waiting for the PC to boot takes a lot time, so a lot of time wasted before you can actually start working. i'm not really satisfied with the standby feature either. sometimes the PC just doesn't resume or i would get an error message. this happens more often and i would always end up rebooting the PC in the end.

    this is my favorite feature on Macs, and i don't know if i missed it but i don't think you mentioned it at all in the article.

    wonderful job overall Anand. i felt exactly the same way when i first got my Mac, being a diehard PC user myself.

    #28, it works on Win98 too.

    Sometimes, these article make me wonder if Anand is the kind of "die-hard PC user" as he claims. For example:

    "Unlike the Windows command prompt, Terminal actually interfaces quite well with the rest of OS X. For example, if you have a file, drag it into an open Terminal window and the entire path to that file will be copied into the window for you. It actually makes interacting with the file system from the command prompt quite easy."

    As does CMD. As it's done for at least since Win2000. Possibly longer. There are lots of small things like these, bordering on being untrue statements, interspersed into these two Macintosh articles (which, admittedly, are good reads).

    It looks like one of your dislikes with the G4 P'Book may have been partially addressed with the brand new lineup. Scolling and panning on the trackpad can be performed with two fingers. Besides, they're just plain faster and cheaper than before. BTW, great review!
  • sluxx - Thursday, February 3, 2005 - link

    Enjoyed the article very much.

    I'll also fifth SideTrack. For $15, you essentially get a new multi-function trackpad.

    When you are typing, in the middle of a word, press alt+esc, you get a list of words that begins with what you've typed. Great for looking up words that you're not certain of the spellings. I imagine it works only for Cocoa apps and not Carbon apps.

    A couple of other freewares that I find useful: Spirited Away that hides selected (you select) background apps after a specified amount of time, and Speed Freak, a GUI wrap of the "renice" unix command. It's especially useful for me on a G3 iBook, but can help making your front app snappier. You can search and find them at www.versiontracker.com.

    My first time here, but looking forward to reading your other articles.

    A couple of PowerBook features not covered in the article but still worth mentioning:

    - Dual displays: an external monitor plugged into the PowerBook can either mirror the LCD screen or act as a second display and thus significantly increase the desktop real estate.

    - Target Disk Mode: start the computer with the 'T' key held down and the computer behaves like an external FireWire drive. Very useful for transferring large amounts of data between machines quickly. (this works to all Macs)

    Both Windows and Macintosh OS's try to "think for you", but there's a fundamental difference in how they do this. Windows *imposes* its monopolistic will all the time, making decisions that it decrees to be the way things should be done all the way from spelling and grammar to where files should be stored, to the web search results. It's very mercenary, patronizing, irritating, and annoying. Apple, on the other hand has a more philosopher-king style, making "kind suggestions" rather than decrees, and guessing what you want correctly, sensibly, and unobtrusively more of the time. Somehow the choices Apple makes feel much kinder than Windows and always make you go "Wow, thanks" instead of "Oh damn, leave me alone." This is pervasive.
