The new PowerBook G4s have arrived! No, they're not the G5-based machines everybody was secretly hoping for, but they do bring in a slew of technical improvements, slightly better pricing and higher clock speeds.
Finally, Apple has built "sudden drop protection" into their professional class of laptops. Basically, if the laptop feels a sudden change in force or a hazardous impact, in a few micro-seconds it will freeze and lock the drive heads as to prevent damage to the most fragile part of a laptop, the hard drive. Once the shock is over, the machine will unlock the drive and continue running. This technology first appeared on IBM Thinkpads and has saved many careless laptop owners a lot of data loss.
Besides force sensors, the new trackpads allow for two-fingered scrolling, a feature previously only available with the use of 3rd-party programs, and no doubt a feature that will be appreciated. Older PowerBook owners are out of luck, as this feature is only for new P'books.
The faster clock speeds are not a HUGE deal, but they're noticeably faster. The 17" PowerBook now has the option of running the monster 30" Apple Cinema Display thanks to a new 128MB video option (the PowerBook minimum is now 64 megabytes, pretty nice). The prices across the line are down a shard, too. The 12" model still misses out on the back-lit keyboards, though the 15" and 17" now feature an improved backlit setup. 5400RPM drives, Bluetooth and Airport Extreme is now standard equipment across the line.
I must admit, staring at my year-old iBook, I do feel a tad jealous, but for my needs... the iBook G4 has done a fine job. I do hope OS X 10.4 Tiger will get along with the slower specs, because from the demos, it looks like it needs a lot of processing and video power.
Apple exec's have said a PowerBook G5 will be "the mother of all thermal challenges." Only time will tell whether some brilliant engineer finds a way to modify the current PowerPC 970, or if a G5-mobile chip gets developed.
For you dose of Apple news, I'm Mike.
