I am borderline geek, but not enough to be a nerd.
Just like you, one day, I had to start and learn.
So, jump in. Bring your Mac along, we are going to play a little and have some fun.  There is no need to worry, I won't send a report card.
After all, the only risk for you is to learn a little something, those little tricks that will make your life easier or make you better are what you do. Jump in!
Mac OS X is a fantastic OS and a lot of features are really cool or helpful and will make your life a breeze ...
I hope you'll enjoy it as much as I do.    

A bit of history:
I started playing with computers a long time ago. For you kiddos, my first computer had less memory & colors than a $2 Walmart watch of today. It was a  Thompson MO5. No CD (not invented yet), No USB (ditto), No 3 1/2 floppy, 5 1/4 Floppy were top notch and expensive material;  Prog were saved on a tape. Yup!, the same type that you'll find in an antic store or in your grandpa 1981 Oldsmobile: Compact Cassette.
Colors? Ohhh Yes, 16 colors and an amazing definition of 320x200 pixels. Each pixel was so big that you could land an helicopter on it.
32 KO memory (Thirty-Two Kilo Octet) powered by an amazing Motorola CPU at one Mhz (that's 3000 times slower than the last iMac). With the Cassette Tape, it was between 15 to 20 minutes to find and load a prog (in Basic, please)
I used to type those prog by hand. To send one to a friend was very simple: As modems where almost science fiction, and the word "internet" was unknown, we had to find a system to send "huge" amount of data: Trip to the post office and send few tapes. A week later, you were up and running ....
If sold today, its price would be about $1,000 (Inflation corrected)
My first "pro" one was a HP Vectra, 80386 at 12Gh and 20 Meg hard drive, MS-DOS 3 and a 13" screen the size of a Thanksgiving rated oven.
So, now that you have smiled , or barfed, quit whining and enjoy your little  Dual or Quad core monster...  Let's make him sweat a little ....

For the Geek of it: Internet

The Last U2 Concert (at the Rose Bowl) on Youtube was a live Worldwide Live Streaming Event and about 10 Million people watched live:
Streaming, Regular Quality is about 135 KB/S, HD is 340 KB/S
Concert Time: 2:21:22
Bandwidth needed live: 1,350,000,000 KB/S or 1,350,000 MB per sec.
That's more internet per second then the entire internet in 1980,1981 & 1982 combined
If you watched it in HD, that's 340 KB/S: Bump up the Bandwidth to 3,4 Million MB/S or in layman's terms: Your 500 GB Hard Drive every 0.00014 sec.

Let's meet again in 10 years when the average home connection should be at few GigaBytes per sec.
