Somewhere out there!

Some detail from Apple about External Monitors resolutions.

When the flat-panel display and an external video monitor are operating at the same time, each is allocated 32 MB of video memory in 64 MB VRAM systems or 64 MB of video memory in 128 MB VRAM systems.

Seems the desktop spanning is built in by default for the Powerbooks. The question is, does having only 32Mb allocated to each screen make a difference?

Update: According to this page:

WHAT ABOUT QUARTZ EXTREME? Some of my programmer friends theorized that the extra video memory should speed up Quartz Extreme functions. I disagreed. I argued that graphics processor speed is the key, not graphics memory size, since Apple’s documentation states you only need 16MB of video memory for Quartz Extreme functions.

I saw an interesting graph on Apple’s Quartz Extreme Page from a benchmark called “Window Move.” I was able to get a copy of a similar application that creates hundreds of buffered, semi-transparent windows in various sizes, shapes, and locations.

This test showed no difference.

Both these Ergonomic USB Keyboards with Intuitive Gesture and Pointing Builtin from TouchStream look like very clever. Plus there is a model, MacNTouch, for Powerbooks

One of the things I’ve wondered about tools like this with Related or See Also search mechanism, is extending their use by Bayesian word analysis. Similar to what is done with spam detection, but as a way of finding related groupings of concepts. Extending this further and allowing local library of tagged information to sync with remote libraries. You might find ways to grow more interesting search tools that look for concepts rather than keywords.

Of course being a professional write its easier for Steven to take notes and key then into his research tool. Seeding his locally tagged concept space. Some times I think it would be nice with one of the various paper books I was reading, of me to use point at a passage, vocalise some notes and have it store itself automatically some where.

Couple of discussions regarding the Powerbook vs iBook question:

* Apple – Discussions – PB 1.33 vs. ibook > noise & durability
* New PowerBook vs. iBook – The shootout.

Good summary in the later link:

* 12” iBook – it’s cheap and very good. If you can’t afford more, get this one.
* 14” iBook – it’s bigger, heavier, and more expensive than the 12”. I still trying to figure out why this is in production.
* 14” Super iBook – it’s bigger, heavier, and slower than a PowerBook. No idea why they make this one either.
* 12” PowerBook – it’s a really expensive, slightly upgraded iBook.
* 12” PowerBook w/ Super Drive – this is a nice model and you might need the Super Drive.
* 15” PowerBook – This is a great computer for the price.

Furthermore, there is some mention that the screen of the 14″ iBook can be blurry. Maybe both a 12″ iBook and a 15″ Powerbook is the sweet spot? 😉

Updates:

* Clamshell mode? – iBook likely to overheat with clamshell closed.
* 6hr Battery Life – Some reports of 6+ hour battery life. Impressive.

Here some tip bits on Powerbook batteries:

• Two pages on batteries at Apple.
• Swapping battery while in sleep mode:- Only the 15″ and 17″ Pb’s can do it because they have enough room for a backup battery for use while the main battery is out.
• Important to read the manual and calibrate battery on the first run.
• Finally, this page on 15″ PowerBook Battery Life Tests is very comprehensive.

Update: A nice page at macintouch with much anecdotal stories about Apple Laptop batteries.

From MacInTouch, here are a few additional notes from our initial examination of the 15″ PowerBook G4/1.67GHz:

* The screen is beautiful, with a big, welcome addition of space versus iBooks and 12″ PowerBooks. (The screen seemed a bit dim at first, until we found the autosensing brightness option.)
* In size, this laptop is not very different from a 14″ iBook but a little more rectangular in shape. It has far more expansion ports, however, from a PC Card/Cardbus slot to audio input and FireWire 800.
* As noted yesterday, AirPort performance was very disappointing in comparison to that of an iBook G4, iBook G4 or eMac. We finally got the PowerBook to connect a bit better by setting the AirPort Extreme Base Station to do 802.11b protocols only, disabling the faster 802.11g option.
* Bluetooth, with file-sharing, is enabled by default.
* In comparison to iBooks (or even better, a PowerBook G3 “Pismo”), this PowerBook’s trackpad button is unpleasantly stiff, although its click is quieter. We haven’t had time yet to explore the new trackpad features, and the trackpad “clicking” option (also available on other Mac laptops) gave us problems with unintended clicks.
* There appears to be no access to the laptop’s internals with the sole exception of memory slots, behind a door on the bottom of the computer.
* Despite its faster processor, the PowerBook is quiet, on par with an iBook or a Mini and a little quieter than an iMac G5.
* Running benchmarks with Energy Saver set to “Highest” performance, the bottom of the computer became too hot to touch, but the stop stayed fairly cool. (The ambient temperature was about 70 degrees F., and the PowerBook was sitting on top of its cardboard shipping box.)
* The operating system is Mac OS X 10.3.7 (7T62) with a Darwin 7.7.2 kernel. Mac OS 9 is an optional installation.
* iLife ’05 is pre-installed on the hard drive (with QuickTime Player 6.5.2), but there’s no AppleWorks nor iWork in the bundle. A QuickBooks “New User Edition” requires registration by phone with Intuit.
* The optical drive (SuperDrive) is a Matsushita UJ-835E, the hard drive a Fujitsu MHT2080AH.
* The Mobile Motion Sensor shuts down and re-enables the hard drive quickly and may cause some data loss in the event of strong vibration.
* The PowerBook can be run closed with external monitor, keyboard/mouse and power supply.
* We encountered one hard freeze, with the SuperDrive spinning and AirPort operating, and we had to hold the power button down until the system shut off, because reset keys didn’t have any effect. The same CD mounted fine after the restart.

Also some insight as to why some people prefer Macs.
