For what it's worth, the default font that LaTeX uses is called Computer Modern.
I know there's already been a bit of anti-LaTeX sentiment in this thread, which is unfortunate because it really is amazing for papers and theses. I was writing my Master's thesis in Word but soon became blocked. What's more, the document had become so big and unwieldy that Word eventually crashed -- and took my document with it!

I was able to resurrect it, but I was so PO'd at Word that I immediately took the plunge and converted everything to LaTeX.
I used TeXShop on my Mac which is a very good, almost WYSIWYG editor (type the codes in one window, see the PDF preview in another, side by side). I took advantage of LaTeX's ability to have individual chapters saved as individual files and then all included into a master file. The reorganization made it all easier for me to manage and helped unblock me, too.
It also made formatting a no-brainer. I just downloaded an existing thesis template from the web, modified it a little bit to meet the particular requirements for my school, and all was done. Chapter headings, page numbering, headers and footers, tables of contents, lists of figures, captions, all properly numbered and referenced. All automatically.
Plus, there's just something magical about taking your document and applying one of the pre-formatted templates for theses, technical papers, etc. and suddenly seeing everything look.. for lack of a better word...
legitimate. Since so many papers use LaTeX templates, mine suddenly
felt like a research paper. That made me feel good.
Also, if you use a lot of math, equations, proofs, lots of footnotes, etc. you will soon come to appreciate how easy it is to make these work in LaTeX.
Writing LaTeX "code" is a bit like writing HTML, so if you're familiar with that, it's not a stretch to learn.
