Huntn, ------> I am not sure why you are bringing it up to begin with. I see your logic, but it's almost like comparing incomparable things. You could downplay the idea of ever watching a film or TV, and instead do something with more brain activity - Like playing Sudoku in a cave for 10 years, or suggest you start doing some sports instead of playing guitar, as it will be better for your healthy and increase your life expectency.
Doing one thing, does not need to cancel out the other, which brings me to the idea that one would just happen to manage their time between playing games and guitar.
I don't like the notion that people try to outplay some activities and things as more or less meaningful than others. I would rather be a fool who "wastes" his life according to academic popculture beliefs, than a creative genius on the drums and a master of the arts, who has a sad life.
In the end we're all going to die, and just enjoying yourself in the moment is all that matters. That WoW will some day be gone? Yes, but that's irelevant - That's missing the point, and a flawed logic you could also use to diminish the worth of the guitar - Because one day you will be to old to play guitar, and you will suck, and all the hours learning it will be wasted.
Or will it?
Original poster:
It's funny how this off track discussion perfectly leads into the WoW discussion about the journey versus the end. People who play WoW and these kinds of games seem to be mixed, on what they prefer. For some it's all about growing, developing and discovering. For others it's about reaching their max(end game) and be all they can be at it.
I think a combination of both is at the best point.
This is why I saw to the Original poster, that waiting for the Cataclysm expansion would be a perfect time to start. Save up your money and buy the game and the expansions, and be ready for it when it comes out. Most likely in November or something!
The game is getting something that has never happened to a 5+ years old game before... A Renaisscance!
The original world is being altered, 3000 new or tuned quests are being added, level experience is being improved, with less boring repetitive quests, and more fun storylines.
Not only that, but many old players will return to play the two new races, Goblin and Worgen, and play the new race class combos. Now many races can be classes they could not before(Tauren Paladin, Blood Elf Warrior, Night Elf Mage, Gnome Priest, Human Hunter, Troll Druid to name a few...).
Not only this, but the guild aspect is being improved, as now you can level up in your guild. Your guild is getting levels now, and actual abillities that help everyone in the guild.
I would suggest seeing Total Biscuit's beta videos to give you an idea of what is in store for Cataclysm and how it will change WoW in a very dramatic way:

So if I were you, I would get ready for WoW when Cataclysm comes out, but in the mean time, maybe you want to play some of the other great Blizzard games that works fine on Mac? Warcraft 3 is a great RTS RPG, that has a cool story - From there you can try DOTA that inspired it or the free to play League of Legends that is a retooling of that, with a Mac client coming soon < All free 2 play.
You could also play Starcraft 2 which just came out, to rocking reviews;

When you create a Battle.Net account, you can talk over Starcraft 2 and WoW. It's like their own stab at a Blizzard community. I haven't tried SC2, but I can really vouch for that Warcraft 3 is a cool game, with a great story, and it's expansion is really fun. It can really set you in the mood for WoW, as you see this cool story with cool characters and a fun world.
And it's also like 5 or 10 bucks! Even though it's over 8 years old it's still among the most played games out there.
