Having had broadband service here for a month come Thursday, I'm
still finding it a luxurious novelty not having to go through the
dialup rigmarole a dozen or so times a day over our sole telephone line
umbilical to the outside world.
The speed is great as well, of course, and it's saving me time -
although one has an unfortunate tendency to just pack more work into
the extra hours freed-up. I'll have to work on that.
Pismo Shortcomings
Another effect of having everyday broadband is that it has
accentuated the performance shortcomings of my Pismo PowerBook as a production
machine. 
I still love the Pismo and always will. It remains my favorite
computer to work with hands-on in terms of tactile "feel", but moving
into the broadband dynamic, its relatively anemic 550 MHz G4 processor,
and especially its lack of video punch, have become the bottleneck in
my workflow, whereas previously 26,400 bps dialup speeds were.
One avenue that has opened up with broadband is streamed video. On
dialup I just never bothered, and YouTube was largely terra
incognita for me. It now works fine - on the Core 2 Duo Unibody MacBook,
but on the Pismo, it's still pathetic. Eight megabytes of video RAM and
that old Rage Mobility 128 GPU just don't cut it.
Another Option
I've experimented with using the 17" PowerBook G4, which the
MacBook displaced as my number one production computer, in
second-string role normally filled by the Pismo, and while the AlBook's
keyboard is fine, I just loathe its abominable trackpad (never a
problem when it was my desktop substitute), and using a peripheral pointing device like
the Logitech TrackMan Wheel
trackball, which is the one I resort to most because it doesn't
require a mousing surface, is still cumbersome away from a desk or
table, and I prefer to use the sublime Laptop LaidBack stand in a recumbent position
when away from my office workstation, where I spend quite enough
time.
Having a wireless router and AirPort has made using computers away
from my desk much more practical, comfortable, and convenient with no
need to stay near a telephone jack, so using the TrackMan Wheel with
its old-fashioned bulky wireless USB receiver seems like a step
backward.
Pros and Cons of Each
Another thing is that while I've never found the 17" PowerBook too
large and heavy on road trips, its extra weight compared to the Pismo
makes it a less pleasant alternative for mobile use around the house,
although it fits on the LaidBack okay. Another thing I dislike about
using the PowerBook is that the cooling fan cuts in intermittently
unless I run with reduced power selected in the Energy Saver system
preference, which I estimate probably gives me about 667 MHz of the
nominal 1.33 GHz. That quiets the fan cacophony, but performance
running OS X 10.5 "Leopard"
is more sluggish than I'm getting with OS X 10.4 .11 on the Pismo,
although it is nice to have Leopard features like Spaces.
By contrast, the Pismo runs consistently cool, and the only times
it's cooling fan ever spools up is under heavy processor load on the
very hottest days in the summertime, 
which is another reason why I love
it. The palm rests also don't get hot and clammy like they do on the
PowerBook G4 (even running at reduced speed).
While I love the aesthetics of my
Unibody MacBook, and the old 17" PowerBook isn't a bad looker either, I
remain unsold on aluminum as an ideal laptop enclosure material. Even
though I'm philosophically inclined to favor "natural" materials, I
have to say that I think polycarbonate plastic has a much more pleasant
tactile feel on the contact surfaces of a laptop computer than anodized
aluminum does. The prospect of a polycarbonate unibody replacement for
the white MacBook is intriguing in that context.
WiFi Dropouts
Speaking of AirPort, which I was a minute ago, I've discovered that
another Pismo shortcoming is that from time to time it will just drop
wireless reception and refuse to reconnect until I shut down and
restart the computer. I can't blame this on my wireless router setup,
because the same phenomenon used to manifest occasionally using the
Pismo with its Buffalo G54 802.11g WiFi PC
Card when connecting to WiFi hotspots. It was a minor aggravation
then, because I didn't spend a lot of time in that context, but now
that I'm using wireless for everyday Internet, it's become a serious
pain.
These connection dropouts don't happen with either the MacBook or
the PowerBook, so it's either something about the way the Buffalo WiFi
card addresses AirPort in the Pismo (or vice-versa), or perhaps an
OS X 10.4 "Tiger" issue. I'm using Leopard on the other
machines.
Back to Poky Dialup for a Bit
Today I used dialup for the first time in nearly 4 weeks because,
running behind schedule, I just didn't have the roughly 20 minutes it
takes to shut down my suite of production applications and OS X Classic
Mode, restart, and then wait for everything to start up again,
particularly reloading open browser tabs at dialup speed. I have to say
that the good old solid hardwired dialup connection was reassuring -
albeit painfully - slow. When I restarted the machine sometime later,
normal function was restored.
Speaking of reliability, I'm happy to report that over the first
month anyway there have been no reliability issues with the wireless
broadband service, which is reassuring. Performance does seem to be a
bit time-of-day dependent, with a consistent slowdown in the late
afternoon and early evening. I'm guessing that is because of more users
logged on sharing bandwidth, although I haven't confirmed that. It
flies late at night, ironically analogous to what I experienced for
years with dialup, although several magnitudes faster of course.
Another irony I suppose would be that dialup is now probably working
better in this neck of the woods, with most users having switched to
wireless broadband. Writing the first draft of this column at 9:42
p.m., still in the slowdown period, I checked with the toast.net speed test
site and was getting relatively mediocre 376 Kb/s throughput. A
subsequent check at 11:50 p.m. returned 1,165 Kb/s, and at other times
of the day I've seen as high as 1,300 Kb/s and change. Hopefully when
the service provider gets more of the promised towers built in this
area, speed performance will become more consistent.
As for my personal dilemma about which computer to use for mobile
duty, I haven't given up on the Pismo yet, As I said, I still like the
feel of it better than any other laptop, particularly the keyboard and
trackpad. I'm still feeling my way, and I guess eventually I'll decide
what's the lesser aggravation to put up with.
