PDAs as a College Notebook?
Eugene asks: "G'day everyone!
Here's the deal, I study Engineering in college and therefore, I have to write down LOTS of mathematical formulae and such. Now I heard that students of Law/English/etc. find great use of various PDAs
as a notebook replacement(that's pen&paper notebook). I'd like to know if there's a PDA software-solution for quickly writing down math expressions( Something like the equation editor shipped with MS-Word - but if possible with a more intuitive way of entering data). All I could find so far are lots of calculators, that do little in the way of easily entering equations and storing them for later review." Well, that would be one less thing to lug around in the ole backpack. Now if we could only get textboox in digital form...
To wit: where the fuck is our electonic paper already? I've wanted it ever since I saw Captain Kirk using an computer tablet some 35 years ago.
PDAs aren't it. Except for a few people who can do 40 WPM without concentrating using Fitalystamp or something similar, there's no practical input for plain text, never mind math. And how can you possibly keep track of your notes on such a small display? (Even the Newton was too small for this purpose. And of course too big to put in your pocket. The worst of both worlds.)
IBM was on the right track with the Thinkpad 700, which folded flat so you could use an electronic stylus instead of the keyboard. Alas, the 486 processor just wasn't up to serious character recognition, and IBM abandoned this option in later Thinkpads.
(The Transnote is interesting, but I don't quite like the idea of having a separate input device.)
Here's what would make Captain Kirk smile. Somebody comes out with a mass produced pad device. Minimum requirements:
- At least VGA-resolution display
- Stylus input
- Enough processing power and RAM to do serious handwriting recognition
- Mass storage of some kind (hard disk uses too much juice, but anything else is probably too expensive)
- Some kind of comm/expandability option. USB 2 would suffice.
That's it. Don't waste money on a color display -- I'm not going to use it to display graphics. And most of all, don't waste a lot of R&D money on software development. Leave that to the hackers. We've all seen what they can do if you just give them the right platform!Ok, what about something now? Well, if you can't spring for a Transnote, there's always the Crosspad, which was an attempt to market the Transnote's input device as a separate product. No longer in production, but you can get them on ebay for about $150.
That really-small, really-cool Sony Vaio device comes to mind... or even an Apple iBook....
You could also look into something like the HP palmtops, or, dare I say it, the Newton.
This is really what the Newton could have become, if it had been given a chance. The problem was that it was waaaaay too ahead for its time!

I too have yearned for such a device...0 0.cfm">Viewpad 1000 TabletPC</a> and can just imagine reading slashdot over a bowl of cherieos at the dining room table. :)

I did mechanical engineering with a math minor... and between that and the Linux hobby I got exposed to LaTeX pretty early. I've never owned a laptop (or a PDA with a keyboard), so I haven't tried to use it for notetaking, but I'll bet with a little practice that's what would work best. And if you decide that it doesn't work for notetaking, it's a good thing to learn anyway. It produces spiffy-looking reports, translates automatically to MathML, is the preferred submission format of most math/engineering journals, etc. You'd want a laptop with a full size keyboard, not some palmtop 2-finger typing thing, though.
I agree, you probably want a solution that allows you to simply write on real paper, but have a copy on your palm. To do this you can use something like the smartpad
or from the seiko web site: here
This thing won't allow handwriting recognition, but will "draw" into your palm as you write on the paper. Combined with using the text entry on the palm this could be what you are looking for. Formulas and pictures can be sketched on the paper, and notes can be written on the palm.
Another bonus is that you can a decent size folder to protect your palm, and carry your mobile, pens, etc. etc.
If you ever drop your keys into a river of molten lava, let'em go, because, man, they're gone.

If the professor used this, no one would have to copy notes off the boad.
In one of my CS courses, there is this one guy in the back that has a PDA with keyboard attachment, and he types in all of his notes into it.
However, it is *extremely* annoying to the rest of us! The keyboard makes that click-click-clack-clack sound, which wouldn't be annoying except for the fact that its in the middle of class.
Imagine if the whole class did that? It'd be as noisy as a touch typing course.
