4K video editing doesn't sound like a "casual" task, not something that the target audience of the Mac mini is aimed at (or at least should be). The Mac mini was meant to be a entry-level computer, not a powerhouse beast in a small package. Apple has recently beefed up the specs, and the price, and I think that was the wrong move. It removed the mini from the original target audience completely. Who would buy what *should be* an entry-level computer, yet pay a premium price? It's just off balance.
