Hey,
Honestly, the Mac mini was my very first mac computer. All the others before the Mac mini weren't mine.
I did Final Cut Express editing on it, along with Dreamweaver, Photoshop & Illustrator. Now I didn't expect it to run it amazingly, but considering the size and power of the computer, that Mac mini was a monster.
If you choose to get a Mac mini, I don't think you'll regret it.
BTW, I'm using a MacPro now, so you can kinda understand what work ive put it thru.
That's just my 2 cents.
