Got any other handy hints?
I am going to get a open lic word-like product.
I just surf the internet, do email and watch an occ video for now. Later I’ll be doing iTunes.
Right now, I note that Safari tells me when a word is not spelled right, but no list of suggested spellings.
To get correct spelling suggestions, use ctrl-click (‘right click’, as it were) on the word. If it thinks it knows the word you are trying to spell, it will give you suggestions.
For example, I mistyped ‘ctrl’ as ‘crtl’. (I always to that, you may have noticed.) ctrl-click offers ‘cartel’, ‘curtail’, and ‘ctrl’.

To turn off cookies, use cmd-comma. You can choose Always, Never, or Only from sites I visit. If cmd-comma does not bring up the Security window, choose it from the top of the window and it will stay there until you change it to something else.
Speaking of security, Safari has Private Browsing:
When private browsing is turned on, webpages are not added to the history, items are automatically removed from the Downloads window, information isn’t saved for AutoFill (including names and passwords), and searches are not added to the pop-up menu in the Google search box. Until you close the window, you can still click the Back and Forward buttons to return to webpages you have opened.
Ok, but how helpful is this, if no one else uses my computer ? I also always close safari when done, and even turn the computer off.
Well, if you don’t want your wife or kids to discover your pissing midget nun fetish it can be very handy indeed! 
It might also come in handy if you happen to use a public Mac, to protect your identity and such. Not that there are many public-access Macs around. I live alone, so I don’t have any reason to use it either. But it’s fun to know it’s there.
Out of curiosity, is this the iMac where everything is cased in with the monitor, or the ones where the monitor sits on an eyestalk? Cause I absolutley loved the eyestalk thing, even though I was endlessly infuriated with the weird problems I would have on those Macs (possibly due to how the university was administering them; all of the ones I used were in a computer lab, and possibly I am just a jinx for Macs)
The Mighty Mouse (the one with the scroll ball) and Magic Mouse both have right buttons, but they’re not enabled by default. Open System Preferences and go to the Mouse preference pane to set the right button to “Secondary Click”. Then, click while touching the right half of the mouse (take your finger off the left side first).
I keep forgetting that I’m using a PowerBook. Yes, if you have a mouse then you can right-click. (I have a MacAlly that I use for work.)
