Which operating system do you use?
If windows, i personally use the combination of MikTex as Tex-distribution, TexnicCenter as Editor and SumatraPDF as Viewer. All those programs are for free. This combination even supports forward and inverse search (you can click in the code and automatically jumps to the corresponding part in the pdf and the other way round).
One thing I really like about this editor, is its ability working with projects. You have one main tex-file, which is always used when compiling. It doesn't matter in which tex file you currently work. This makes it super easy splitting up your document in several files.
Other editors although have a similar feature, but not as easy to use as in TexnicCenter.
It's LaTeX.
Tex uses fonts from the Computer Modern family by default, so you might be able to grab that as a stand-alone font.
If you want to get into using LaTeX, it is one of those things where setting up all the software and libraries to get it working is a real pain, but once you get it to work it is wonderful. Sort of like running a Linux system.
I use TeXnicCenter for editing stuff and the MikTeX distribution (which TeXnicCenter recommends).
You can do all sorts of fun things in LaTeX, but it takes a lot of messing around and Googling to find out how. I wouldn't recommend looking into it while exams are pending.
I use TeXnic Center, which imports and installs packages for you, but I'm not sure that's the easiest one to configure and install. (I can't remember; it's been so long since I installed it)
LaTeX will do this, but it is not the easiest piece of software for beginners...

If you are on windows this is a nice editor for LaTeX. http://www.texniccenter.org/
Once you get latex working you can use \resizebox{\hsize}{!}{One line of text} \resizebox{\hsize}{!}{Next line of text}
I have been using TeXnicCenter on my (external) QHD display, and it looks fine on a 25" screen. Not sure how well it would do on a small screen, but I think the font sizes can be changed in the settings, so you could give that a try.
Back when I was an undergrad in Mathematics, I took live notes in latex. I used the Texniccenter with a few custom auto completes and MikTeX on Windows 7. That made me fast enough to produce decent lecture notes on the fly. When I felt like it, I even build some figures afterwards.
On high time, I had a few friends sitting next to me, all reading my live notes on there tablets/whatever and telling me when I made a mistake.
Don't know ... for my PhD thesis I used TeXnicCente and it was quite a charm. It really helped without getting in my way. I tried using a commercial Latex editor, Lyx, and the KDE one but I preferred Texniccenter .
There is also https://tex.stackexchange.com/questions/250472/texniccenter-adobe-reader-dc. Honestly, maybe someone here happens to know but it sounds like an issue for the texniccenter mailing list http://www.texniccenter.org/support/.
I use TeXnicCenter. It's my personal favourite, a lot of people in my research group use it as well. Another option which is much better than TeXWorks IMO.
Coupled with Sumatra PDF it is awesome.
I use the open source TeXnicCenter to edit LaTeX. It's pretty nice, although I must admit I have not really tried a lot of alternatives. It only runs on Windows though.
I also use Zotero for reference management.
I've heard good things about TeXnicCenter - my girlfriend just finished her Ph.D. thesis using it. There was a fair amount of cursing, but that was mostly at Mathematica.
Under no circumstances use Scientific Workplace! The TeX it produces is horribly mangled and not easy to use by others. Truth be told, SW is What You See Is What You Get, whereas TeXnicCenter isn't - but the cycle from pressing the 'compile' button to having the finished PDF pop up is short enough not to get in the way.
LaTex isn't elitist. It is just a bit different to learn (to look up how to format something) then (wildly clicking through menus wasting a lot of time in) WYSIWYDNW (what you see is what you did not want)-programs like word. Anyway there are programs like Texnikcenter offering a bit of the processor-world.
For anything technical at least LaTex always will be the better choice. Let the Geisteswissenschaft-majors fiddle with essays in Word/OpenOffice :)
