So, I've been heavily considering a Macbook Pro with a 17" screen. Knowing that Intel's Santa Rosa/Barbara/Ana/Cruz/Whatever

is right around the corner, I'm certainly going to wait on any final notebook decision. Given
Apple's impending next big cat Leopard release, I'm going to wait at least that long. Besides, that puts the MS Office 2008 for Mac release within reach, too (I'm an advanced MS Office user).
However, I just couldn't prevent myself from spending almost 2 hours at my local Apple Store last Saturday getting familiar with a Mac for the first time in 12 or 13 years. Certainly, parts of the interface rock, and I've enjoyed the Leopard demo at Apple.com.
However, the part that amazed me the most was iLife. That application suite simply rocks. Even the integration with the upgraded applications like Final Cut Express was amazing. We made a quick movie from pre-existing pictures and video, plus some video we filmed right in the store on the MBP, and it was mindblowingly simple.
So, my question for this well-regarded crowd is whether any software exist on the PC side of the world that does what iLife does? Is it worth switching just for this?
