I have been using the Fujitsu T900 tablet for over a year. I use Microsoft OneNote
and do all my homework on it. It is actually MUCH nicer than pen and paper as far
as I am concerned.
I just draw my equations, I don't convert them to equation typescript. I can do very involved calculations and proofs, things like double/triple integrals, etc., on this and
it is very nice. You can use the lasso to select part of your work and then shrink it and tuck it someplace handy. You can also use different colors and thicknesses. It naturally
formats to an 8.5/11 inch page. If I am doing intermedate caculations, say for a trig identity, I can take the less important part and shrink it down to a barely visibile dot.
It is out of the way, but if I need to look at it later, I can just lasso it and enlarge it
and all the detail is still there.
To erase a mistake, you use a back and forth horizontal gesture, and the stroke you do it
on is gone. There is also a large, medium, and small eraser that will take away just
what you touch with it--like in MS Paint. You can also undo and redo quite a few times.
When the algebra gets involved, you can cross out with a very find red pen and you can
still easily read what was crossed out. You can also cross out with blue and green pens, too.
I use red for terms that cancel, and blue for terms that combine. it really helps prevent
It also organized the work very neatly. You can create a "section group"--a kind of a folder, and name it for the chapter, and you can create subsection groups for the sections in the chapter, and sub section groups for notes and exercises. For exercise, you can create section, name it for the chapter/section, and then have individual pages in the exercise.
I remember fondly the days when I could do 10 or 12 problems on one page. Now I am
doing 2 pages per problem...!!!
It keeps track of dates, etc.
You can even do rudimentary manual graphing. It supplies a 2 dimensional axis and a 3 dimensional axis that you can pull down and drag around, and stretch. It will draw lines, arrows, circles, squares rectangles, triangles, and a couple of other polygons. It can be
set to snap to a grid or not, however, snap only works when you are creating something,
not when you are moving things.
It does do calculations but it is a real pain and not worth it-- and it won't graph equations, you have to do that yourself. But the graphing it does do is a bit of an improvement over pencil and paper. It rotates figures 90,45, and 180 in both left and right directions, but is not a cad system. I really wish it would allow you to specify degree of rotation, but it doesn't.
However, you can get clever. For 3space, it gives you the Z and Y axis and you can adjust the X axis to any angle you like. However, there are no rulers on the axes. The grid
supplies the ruler for Y and Z, and for X I just draw circles centered at origin and it the
circles give me my ruler for the X axis. It works OK but is kind of tedious, but still better
than pen and paper. One nice thing is for 3D figures, you can make wireframes for cylinders very easily. Eg, if you are doing the cylinder z=y^2, you can draw 1/2 of the parabola by hand, then copy it, paste it somewhere, flip it horizonally, then move it
up to the original parabola, and you get a nice neat symetrical parabola. Then you can
copy the whole parabola, paste it somewhere, change the color to a very light pastel
color, copy that and then past it repeatedly, moving slowly down the X axis. It creates
a very nice 3d wireframe effect that helps visualize the 3D. This is especially nice
when it is NOT a circle or parabola, but something irregular. Not as good as
Mathematica, but definitely better than pen and paper.
It supplies a number of different background grids, and lots of pen colors and highlighters.
Writing is a little tricky because there is no resistance to the pen tip, so it flies. It took
me a little practice to make nice neat numbers and letters.
But, if you are writing a long equation, series and you run out of room on your line, you
can simply lasso the whole thing and "smooge" it over (shrink in horizontal direction only)
and for a 7" of line, you can shrink it back 2 inches and it is still quite readable.
If you need to lable the rectangular coordinates for a point, e.g., (root(3)/2, 1/2), you can write them big, then lasso them and shrink them down very small and move them to your graph. If you make them neat when they are big, they shrink down suprisingly small and are still readable.
Of course, you can select and move stuff all over the place, you can cut, copy, paste,
etc., everything goes to the clipboard. If you don't like the thickness or color of something
it is easy to change. You can customize the ribbon so you have your favorite commands
available close at hand.
I also have a reference page that has hand-drawn figures I need, like sigma, gradient,
etc. I just copy them from there and then use them on my page if I am doing that kind
You never have to save with OneNote, it is constantly saving for you in the background.
I keep my files on my file server, a different W7 computer, and it syncronizes
automatically with that server so I always have a backup.
You need a fairly fast computer with some memory. I have a CORE I5 and it works well.
The tip of the pen is about 1/8 of an inch from where you are writing, which is a downside,
but after a while, you get the hang of it and you forget about it.
By the way, I don't find that it interferes with my ability to write on paper with a pencil
eg. for an exam. In fact, my pencil and paper writing has become slightly neater.
If anyone is interested in discussing OneNote and the wacom tables, I would like to share (and receive!) information.
