some things you should know:
1. Drag your Applications folder to your Dock (after the divider line). It will now work like your start menu. Just right-click it instead of left (if you have two-button clicking enabled). I also recommend moving your Dock to the left side--out of the way of all scrollbars.
2. Customize! Look through everything in System Preferences, and in every app's own Preferences, and in every app's View menu. Lots of powerful choices.
3. Try the option key. Option clicking is a common shortcut that does different things. Option-drag a file in Finder to make it Copy. (Or Command-Option drag to make a shortcut.)
4. Command-Shift-3 to take screen shots, saved to your desktop. (Or advanced mode: Command-Shift-4. Now drag a box around what you want--OR control-drag to Copy instead of saving to desktop.)
5. Drag-and-drop. Just about anything on the Mac can be done this way. Click and HOLD on selected text before you drag, and you can drag the text to another program or even to your desktop. Drag the "clipping" back later--it's like copy and paste. And lots of apps have other uses for dragging an icon or file from one place to another. (Click and hold on the littly "proxy icon" in a document's title bar, and it's like you are dragging the whole file: you can even move an open document to another folder that way.)
6. Command-click in a document's title bar (or Finder window title). Bingo--instant path. Select and go.
7. Use Exposé Show All Windows. Put it somewhere easy like on your lower-left screen corner or your middle (scroller) mouse button. A lifesaver for switching windows. And windows in Exposé are still live and changing: you can use this to keep an eye on several apps at once.

9. TextEdit (in your Applications folder) can Open and Save Microsoft Word documents (if not too complexly formatted).

Note re price: Macs don't cost more anymore. If you find a name brand PC cheaper, it's a pretty sure bet it is missing something expensive that the Mac comes with. People like to look at one or two obvious specs and assume the other features must be alike too. Not so--the devil is in the details, and Macs are LOADED, from hardware I/O to quiet design, to great software bundle. (You can however get a name-brand PC cheaper than a Mac: you can get a really stripped down, poorly-equipped model. Apple doesn't offer anything that low-end, just the $499 Mac Mini.) And of course Macs have no viruses yet, and that's not likely to change very much.
