I have been "just about" to buy a Mac since late 1984 when a friend's parents bought him a newfangled thing called an "Apple Macintosh".
Well, 23 years of being on the verge is just about enough. A dinner with Mac users (thanks Gen, Dice and Jon!) finally pushed me over the edge and so I went out and finally made the commitment and bought a 15" MacBook Pro.
Now I can finally see what all the fuss is about.
