I got the Aluminum 20" iMac with 2 Gb of RAM. I love it! I run Final Cut Express 4, Adobe After Effects CS3, Adobe Photoshop CS3 Extended on it without a hitch. I just got the Canon HF100 AVCHD Camera and it works great with Final Cut Express 4. I keep all my media on an external drive to keep a good amount of my internal drive clear for editing. I then backup my raw footage to DVD and backup my projects to the external drive. The finished videos also go on the external drive. Now I just need redundancy so in case that external crashes. The screen on the iMac is beautiful but there is a gradient to it that may bother some when it comes to color accuracy. I'm aware of it, but it doesn't affect anything for me.
