Subject: Comments on Powerbooks and Duos and some PC laptops
Message-Id: <737408765/rick@MIXO.SOAR.CS.CMU.EDU>

Dr. Bovik:  Here is the result of my post about standard Powerbooks vs.
the new Duos.  

I ended up buying a Duo 210, primarily for the great price, Macintosh
compatibility, and compact size.

------------------------------------

In addition to these responses, I also talked to Peter Lee, who has used
both the Powerbook 170 and Duo 230.  He shifted to the Duo mainly
because it has higher memory capacity (maxes out at 24 meg). He likes
the Duo's overall size (thought that the slimness was even a bigger win
than the reduced weight), but not as thrilled with the screen and
keyboard, which are both somewhat smaller than the Powerbook.  Also, the
active-matrix display, which is a big improvement, is not yet available
on the Duo, but is available on the Powerbook 180 (replacement for 170)
--but for alot of money.

Rick,

I just bought a Duo after intensive market research and comparison.  I
had the same pros & cons as you mentioned, but the light weight (btw
it's 4.2, not 4.7 Lbs) dominated.  I have 3 pages worth of listings of
PC laptops that you can look at.  The only ones that were as lightweight
were quite esoteric and I did not feel comfortable trusting them.
Alternatively, the true-blue IBM thinkpad was quite recommended, but is
not as light.

Ralf Brown, who is apparently a PC guru and enthusiast, told me that
several PCs now exist in this weight range.  Specifically he mentioned
Zeos (sp?).

Btw, Apple reduced the Duo price by 18% this week.  It now sells at the
comp store for $1485 - quite cheap, I think.

Docking: you are probably aware of the 3 apple-made docking options:
Dock, mini-dock, floppy adapter.  In addition, E-machines makes several
types of docs, which differ somewhat in their capabilities.  They have a
model with NTSC output, but w/out SCSI, and another one with nuilt-in
ethernet card.  Dock prices are going to come down soon, and new docks
(by apple or by 3rd parties are very likely to show up very soon, so I
wouldn't buy any dock now if it is not necessary.  You can get alone
with 2 Phone-net connectors (~$8 each), which will connect you to the
mac of your choice.

If you want to play with my Duo, stop by my office.

Rick,

The latest issue of MacWEEK has an article on the Duo's:
apparently they aren't selling well & Apple is dropping the
price.  Reasons cited are the limited selection of docking
options and lack of active matrix screen.

Anyway,  if you decide to go Duo, it might pay to wait a
while.

Having been given a powerbook by my department, I'm an "uninterested"
user per se, but have become *quite* attached to my powerbook.   Last
night I spent some time watching someone try to use a duo, and I'd favor
the powerbook for a couple of reasons:  

1) floppydrive & scsi interface. 

2) the weight seems to make it a little easier to use as a 'laptop" as
you have something a little more solid to rest your hands on  when using
it in your lap (as I've grown fond of doing....).   

I'd suggest trying the "lap-top" test yourself with both, as the duo
appears a little too little (small and light) to be comfortable, while I
*really* like the keyboard on the powerbook and the lap-top-ableness of
it.  on the table/desk - it's doesn't really seem to be noticible.  

my $00.02,

Just in case you didn't know it, OzTex is a Tex/Latex
system that runs on the Mac. I haven't used it so I
can't give you any more info. I believe though that it is
free from one of the various MAC archives.

Hi Rick,

I have a powerbook, but I got it before the Duo's came out, so I can't
offer any wisdom on that score. However, I use gnu-emacs on CS
machines and transfer files a lot, so I can give you a recommendation
there: I user a mac emacs-lookalike called Alpha. It's shareware,
ftpable from the main mac archive sites. It's customisable, although
the syntax is TCL, worse even than emacs lisp. It comes with a
reasonable latex mode that loads automatically with .tex files, and in
general has the same keystrokes as gnu-emacs. When you save files, it
can save in Mac, Unix or MSDOS format, and if the file is in Unix
format it keeps it that way. This means you don't have to worry at all
about file format when you transfer. At school I hook the pbook up to
appletalk and transfer with a Mac ftp program. At home I use the rz
set of commands over my modem, just because it's faster than ftp over
slip.

so there you go,
Jim

Rick,

Now, I don't want to come out sounding like an OS/2 bigot, but here's my
proposed solution, and I'm not sure how much $$$ would be involeved.  

You can get an IBM ThinkPad 700c, I believe thats the model number, its
got an active matrix color display that (I think) runs in XGA-2
resolutions, which are 1024x768x256 and 640x480x65k.  I'm sure its a
80486, but I'm not sure on the megahertz, most likely its 33.  Now, you
would obvisouly get a large hard drive for you thesis work, somewhere
>=120 megs and ample RAM, at least 8 megs.  Now, you get OS/2 2.0 and/or
OS/2 2.1 when it comes out.  Depending on what you want to do, it will
take 15-30 megs of your harddrive.  But, here are the bonuses that it
offers you:

Runs all/most DOS applications
Runs all/most Windows 3.x applications
Many gnu utilities have been compiled for it (gcc, and gnu-emacs to name
the two most popular)  
TCP/IP for OS/2 from IBM

The last entry is the one that I really want to stress.  Its a wonderful
product, gives you full network access and makes your PC look more like
a workstation on the net instead of this disgusting kludge.  Along with
the standard TCP/IP functions, it features things like an internet demon
so you can FTP and TELNET into your computer!  It also comes with a
sendmail demon so that you can have e-mail delivered right to your PC. 
Also, you can get an X11 server for it that runs X applications
seamlessly with your OS/2 applications (i.e. on the same screen -- if
you wanted to -- you could have MS Word for Windows, DOS games running
in a window, Gnu-emacs for OS/2, and an xterm which is a telnet to a CS
machine.  Mind you, thats on the same screen, at the same time.  Oh, the
TCP/IP from IBM also supports SLIP, so if all you have is a fast modem,
then you'll be just fine.

First off, I would warn you that the computer store here knows nothing
about PC's and OS/2, so do your own research and don't rely on what they
tell you.  Make sure you know what you want before you go down there to
order.  

For prices, I'm not really sure.  Assume something in the range of $75
for every meg more memory from the base that the machine comes with,
$150 for OS/2, $150 for base TCP/IP and $100 for the X11 extension (NFS
and Kerberos are also available for another $100)  All the gnu utilities
are free, of course, and I'll tell you where you can FTP them from.

If you are a die hard gnu-emacs person, get a 486 clone laptop.

I got a 25mhz 486SX, 8mb ram, 200mb disk for about $2k.  I also got an
ethernet adaptor that plugs into the parallel port for $300.  No
messing around with serial cables or floppies.  I hook it up to the
net, configure TCP/IP, and use ftp.

On the downside, the box I got is a bit on the heavy side and burns
batteries pretty fast.  I got it to get work done on long trips; I
don't use it on planes and leave the battery at home.  Also, TCP/IP
can sometimes be a hassle to configure if you don't know what you're
doing.

386 laptops are usually cheaper and the low power models don't burn
batteries as fast.

You can run Berkeley Unix or dos.  There is a gnu-emacs clone that
runs under dos and I think there is a version of gnu-emacs that runs
in 32bit mode under dos.  It's also much easier to get drivers for the
ethernet widgets if you run dos.

Subject: Duo vs. Powerbook?

Rick,

I was an avid Mac user, but I bought a PC notebook a ways back (I couldn't
wait the 3 month delivery time for a Powerbook).

Macs are certainly more pleasant to use, but you can make the PC look much
more like a unix environment. 

On my little screen, I don't want to waste any space on windows, for example.

On PCs there's this thing called EPSILON which is a great emacs clone. You
program it in a C like language, rather than LISP, but I haven't done much of
that. I have the bindings set up to look exactly like gnu on my workstation. 
The other cool thing is I can switch fonts on the fly and get 50 lines of text
on the screen at once. It's pretty small on the 9" display, but its readable
(just wouldn't want to do it for a long period of time). A disadvantage to
WYSYWIG things on the Mac is its harder to change fonts.

There's this Mac thing called ALPHA which is sortof emacs like. Lots of people
around like it.

The advantage to PCs is that the hardware is generally more bang for the buck.
One I think is interesting is the Dell 320???, which only weighs 3 poinds. I
saw it at Price Club in New Jersey for $1200. If you only want a machine to
run emacs, you don't need much computes (I think the 320 has a 386SL though). 

I personally find the Powerbooks (170s & 140s) way too big and heavy. Size is
really important to me. The 180 screen is really nice though. (I find the Duo
screen underwhelming).

Good luck.

Mike

I have a PB 140.  I think that the Duo is the way to go.  Unless you
need printing and floppy from remote locations (where you won't be carrying
a dock.)  I think I would drag mine around more often if it was that
size (almost half as thick -- this is actually more important to me than
the weight.)

I do this all the time.  I use the Alpha text editor on the Mac, that
is pseudo-emacs like (not really, but has tcl!).  I use either the modem
(when transferring at home) or a program called "Fetch" when plugged into
the network... no probs!
