You guys are judging something you don't even know. Let me explain.
When you're saying, "the iMac should have been netter at photo organization or home editing", what do you mean ? Better than what ? Have you actually researched to find what software was included on this Sony computer ? What's the point of saying iPhoto does a better job if you don't even know what it competes against ? Not all Windows software is bad, so why can't you seem to think that maybe, the Sony comes with useful ones? Not only that, but have you actually tried Sony software (and 3rd party software included)? to be honest, I haven't. But that's why I'm not going to say that it sucks or that it's not as good as Apple's.
Also, you do not question anything when the iMac is judged by the author of the article better than the Sony, but you comment on almost every good grades awarded to the Sony. Funny, isn't it?
Anyway... I did the research and came out with intersesting info.
On Sony site I found not the computer they're talking about, but one called MXS20. Must be the new one, since it is the same price as the MSX10.
As in any Sony computer, you get a bunch of Sony software, for picture and video management, and this one also includes Photoshop Elements, which may explain why it was well rated when it comes to photo management and touching up. That and the memorystick slot which makes it simple to use sony cameras.
For the audio part, Sony includes a MD recorder, a FM receiver, and a set of "two-way wood-enclosed" speaker. I wouldn't be surprised if they sounded better than the iMac's Harman Kardon. And it also has S/P DIF inputs/outputs.
As for video editing, included is Premiere LE, which provides more functionnalities than iMovie which, on the other hand, is more simple. I guess the number of points you give this category depends on what you think is more important. Also, the Sony also supports TV input and analog input, which makes it even more like a digital hub than the iMac. You can actually turn it to a digital VCR and record TV shows on a DVD.
Oh, and when it comes to watching a video, I just wanted to point out that any PC work as Taft decribed it : double click, and hit play. Actually not, it starts automatically. And browser integration is there, too.
As for the specs (keep in mind that the one that's on Sony site is not the one discussed in the article), it's a P4 2 Ghz, 512 Mb DDR Ram, 120 GB HD. Not bad.
Finally, I'd say we don't know much about the article, except for the results. No word on how they were tested... And it is, IMHO, not enough to draw conclusions such as 1600 $ (btw, 1500 $ now) will only get you two points... that would not take into account MD recorder etc...
