If you want to edit home movies, the Mini-Mac is going to be slow; unless you are doing the most basic work. Now, I LIKE the Mac Mini; but first you must understand what it is, and what it is not. It is NOT comparable to a higher powered PC; which many people want to do. Benchmarks will illustrate the difference between processing power, memory bandwidth and limitations imposed by a cheaper design.
But more interesting, is what the Mini-Mac IS. It's small, streamlined for use not only as a central hub for a home theater (small, quiet, DVI port, ethernet, Bluetooth), it will lend itself to using your home theater to send email, send/recieve/record home movies and also accept HDTV movie downloads, as it supports both Blu-Ray and HD-DVD HDTV movie formats; thus competing in the same field as Hollywood Video; but in an area that Hollywood hasn't even began to explore - Broadband movie download rentals. While the video stores will find themselves re-living the Beta/VHS wars; and stocking movie versions in multiple formats (VHS, DVD, Blu-Ray and HD-DVD); the Mini-Mac will accept all of them from the internet. Naturally, as one would expect, DCMA will be there to (very short term) prevent people from ripping the material to DVD format. But, this is an revolutionary change in the way we will watch movies.
Hollywood has already started "legal" Broadband movie downloads but only for the MS community.
