I love all my Apple stuff, from my iPhone (can't live without) to the iPods we all have, and our iMacs. Very easy to use and quick, quick, quick! I love the way they all work together effortlessly.
But I do have to say is if you do Apple whether it is your iMac or Macbook it is way easier to use all Apple products with it such as buying an iPod or iTouch and using iTunes instead of any other brand MP3 player. My son bought a few MP3 players and it took forever, after hours of searching the net to figure out how to transfer songs, movies.... on to the player as Mac has another music format for music files. So it was converting, adding programs... and much of the software that comes with a lot of the players is made for PC only.
A lot of games and programs are not made for Mac as well and if they are they are more expensive and fewer compared to PC. But after all that I still LOVE all my Apple stuff and feel it is worth it for the use and ease of their systems.
I just bought a HP notebook yesterday just to surf the net in bed and after years of all Mac. Boy, I'm not having fun with how slow it is, all the Norton pop-ups, all the time it takes for windows to start, shut down (Mac is almost instant)..... I just wish I could afford the Macbook right now.
