My four year old MacBook was becoming full of pictures and videos, primarily of my baby relatives. The HD was literally at the limit, plus the HD was getting a bit sluggish with age (despite a full wipe and re-install of the OS about a year ago). I'm getting a nice tax refund, so to I decided to splurge and replace it -- though I can't afford a laptop and still wanted an Apple, so I got the 21 inch iMac.

24 hours in and it's simply stunning, just a great user experience and design all around. I was initially suspicious of the wireless keyboard and mouse, but it's proving to be really smooth and makes my desk feel less cluttered. The wireless, buttonless mouse can even detect whether I'm making a right click, left click or moving my finger to scroll.
The OS is fast, light and smooth. Plus the design of the thing (as an all-in-one dekstop unit) is superb. Maybe I've just been using laptops for the past seven years, but the large screen is brilliant and sharp. Overall, I highly suggest the iMac.
That said, I must add a note about Apple fanboys from my trip to the Apple store. They are absolutely ridiculous. People were streaming in pretty steadily to play with the iPad. Those who bought it were like crack addicts getting a fix -- literally they were taking their new iPads and running into the corner of the glass-and-wood store to unbox the thing like maniacs. If you want to steal an iPad, go to a NYC Apple Store and snatch one from someone walking out. They'll be too high to notice at first.
But I did try out the iPad for a bit. Overall, it's literally a giant iPod Touch with a nicer on screen keyboard. The browsing certainly looks good, but then again it looks better on my desktop where I can actually view videos with Flash. The thing is also heavy. I can easily see a bunch of techphiles and yuppies buying it out, thinking it will make their lives sleeker and more efficient (I can sit on the couch and read the news online, instead of my desk!). But really, don't bother.
