This might be slightly off topic, but does anyone know how to change the size of the pages of a file that is already in pdf format? So, put simply, I have pdf's in regular size but need them in a smaller size so they are easier to read.

Use CutePDF to crop the page. (Crop = to cut off crap from the top and bottom. I believe that's the actual etymology.) Then run it through RasterFarian. Reflowing, copy&pasting into bookdesigner, or OCRing are also possible but are much more involved. However, they'll let you make the letters even bigger.
Natch and kovigdoyal, you are completely incorrect.
GUI applications, the vast majority of times, offer much more functionality and are much more complex (and the fact that they make you feel like they're not is the whole point!). I have no idea how you can think otherwise (perhaps, kovigdoyal, you've spent too much time using Linux guis which are typically jokes meant to passify the "n00bs"). Again, you usually loose scripting (but not with tools like CuteFTP or MS Word. Word, in particular, is exceptionally scriptable), but I'm just talking about what a specific application, such as ftp, lets you do.
Take a look at the
man page for FTP. It's pretty long. Yet CuteFTP is still going to let you do far more. (Its Settings page alone probably has three times as many options. And these options are logically organized, rather than dumped alphabetically.)
Also, kovigdoyal, Word was not designed for typesetting! You must compare Tex to a publishing program like QuarkXpress or Adobe InDesign. Typesetting with Word is very difficult.
The more important thing regarding FTP and Tex: it's possible to do a lot with them "in theory" (like when coding html with notepad), but in practice it's so difficult that none of the features are used. GUIs, especially latest-generation GUIs like in Word 2007, not only have many more features but they lead you to actually use them. That is what counts in the end!
To take an even more powerful example, WYSWYG html editors let people create very complex webpages (such as this forum) but they do NOT let you do anything that notepad can't. In fact, I'd even say notepad/vi is more capable "in theory." Yet I would pay you $100,000 to rewrite this message board with notepad or vi. And if you take me up on the offer (and actually succeed), you'll be lucky to end up earning minimum wage.
